What is 2,6-Dichlorofluorobenzene?
2,6-Dichlorofluorobenzene is a benzene ring carrying a single fluorine flanked symmetrically by two chlorine atoms, formula C₆H₃Cl₂F. It belongs to the mixed halogenated aromatic family that bridges chlorobenzene and fluorobenzene chemistry.
Its value as an intermediate comes from the combination of two chlorines and a fluorine on one ring, a substitution pattern used selectively in agrochemical and pharmaceutical building-block synthesis where the symmetric 2,6-dichloro-fluoro arrangement is specifically required.
Commercially it is produced through halogenation/halex-type chemistry starting from a chlorinated or fluorinated benzene precursor, with isomer control maintained through the synthesis and purification steps.
Handling follows standard precautions for a halogenated aromatic liquid — chemical-resistant gloves and eye protection, adequate ventilation, and storage away from incompatible materials.
Why 2,6-Dichlorofluorobenzene specifically
- A specific halogen pattern. The symmetric 2,6-dichloro-fluoro arrangement is a building block that related mono-halogenated benzenes cannot substitute for.
- Agrochemical building block. Used in selected crop-protection intermediate syntheses that are designed around this exact substitution pattern.
- Pharmaceutical intermediate. A building block in fine-chemical and active-pharmaceutical-ingredient synthesis routes.
- A versatile halex/substitution platform. The chlorines and fluorine each offer distinct reactivity for further functionalisation.
How 2,6-Dichlorofluorobenzene is Manufactured
2,6-Dichlorofluorobenzene is made through halogenation or halogen-exchange ("halex") chemistry starting from a related chlorinated or fluorinated benzene precursor, so supply tracks installed fluoroaromatics capacity rather than a generic chlorobenzene stream.
- Precursor selection. A chlorinated or fluorinated benzene feedstock is chosen to match the target substitution pattern.
- Halogenation / halex step. Controlled reaction conditions introduce or exchange the halogens to give the 2,6-dichloro-fluoro pattern.
- Isomer separation. The target isomer is separated from other halogenation products by distillation.
- Purification. The separated fraction is purified to the target purity level.
- Quality release and packing. Assay and isomer purity are confirmed against specification before the batch is packed and released.

Behaviour in the process
2,6-Dichlorofluorobenzene's reactivity pattern is what agrochemical and pharma intermediate producers are buying:
- Differential halogen reactivity. The chlorines and the fluorine each offer distinct pathways for further substitution chemistry depending on the target molecule.
- Thermal stability. Stable under normal storage conditions away from heat and incompatible reagents.
- Irritant classification. Classified as a skin and eye irritant with respiratory tract irritation potential — handle with standard PPE.
2,6-Dichlorofluorobenzene and Related Halogenated Benzenes
Choosing between related di- and tri-halogenated benzenes comes down to exactly which halogens, and in which positions, the target synthesis requires.
| Material | Substitution | When it is the right choice |
|---|---|---|
| 2,6-Dichlorofluorobenzene | 2,6-diCl, 1-F | Routes needing the symmetric dichloro-fluoro pattern |
| 2,4-Dichlorofluorobenzene | 2,4-diCl, 1-F | Routes needing the asymmetric 2,4-dichloro-fluoro pattern |
| meta-Dichlorobenzene | 1,3-diCl | Routes needing a dichlorobenzene with no fluorine |
| 1,2,3-Trichlorobenzene | 1,2,3-triCl | Routes needing a trichlorinated pattern with no fluorine |
Stated plainly: a synthesis built around the symmetric 2,6-dichloro-fluoro pattern needs this specific isomer — a different halogen arrangement is not a drop-in substitute.
Industries We Supply 2,6-Dichlorofluorobenzene To
The same halogenated-benzene intermediate feeds an agrochemical producer and a pharmaceutical intermediate plant. What changes is the downstream functionalisation chemistry and the documentation each requires.
Where 2,6-Dichlorofluorobenzene is Used
In downstream functionalisation
2,6-Dichlorofluorobenzene is carried through further substitution or cross-coupling chemistry to build the target agrochemical or pharmaceutical active ingredient. The symmetric substitution pattern simplifies downstream regiochemistry compared with asymmetric isomers, which is often exactly why a route is designed around this material.
Need a specific purity or isomer grade?
Tell us the purity and isomer-purity grade you need, your downstream chemistry, the packing format you can receive and the annual quantity. We will come back with a price, a lead time and a sample COA.
Quality Control & Testing
Every lot is released against a batch-specific Certificate of Analysis, with isomer purity reported alongside the main assay because carryover of related halogenated byproducts affects downstream reaction selectivity.
- 2,6-Dichlorofluorobenzene content — by GC assay, the primary grade measure.
- Isomer purity — related di- and tri-halogenated byproduct carryover, reported because it affects downstream chemistry.
- Moisture content — measured because moisture can affect downstream reaction yield.
Common Process Problems & Likely Causes
| Symptom | Likely cause | What to check |
|---|---|---|
| Off-target substitution product | Isomer carryover from the upstream halogenation | Isomer purity figure on the COA |
| Poor reaction yield | Moisture or trace oxidative impurities | Moisture content and assay on the COA |
| Unexpected side reactions | Trace unreacted precursor or byproduct carryover | Full impurity profile on the COA |
Packaging, Storage & Shipping
- Standard packing. Drums or carboys sized to the order quantity, with bulk options on contract supply.
- Moisture protection. Keep sealed and protected from moisture ingress during storage.
- Temperature control. Store in a cool, dry, well-ventilated area away from direct sun and incompatible materials.
- Material compatibility. Avoid contact with strong oxidisers and strong bases.
- Transport classification. Confirm the UN number and transport class against your own current SDS before shipping — published safety-data-sheet sources for this specific compound did not report a confirmed UN number at the time this page was drafted. Do not rely on a figure that has not been verified against your own supplier's SDS.
Hazards & Safe Handling
2,6-Dichlorofluorobenzene causes skin and eye irritation and may cause respiratory irritation. Standard precautions for a halogenated-aromatic liquid and good laboratory and plant practice apply throughout handling.
- Skin and eye contact. Chemical-resistant gloves and goggles are standard practice; rinse thoroughly with water on contact.
- Inhalation. Use adequate ventilation; avoid breathing vapour.
- PPE. Chemical-resistant gloves, safety goggles and, where ventilation is limited, a suitable respirator.
- Full hazard statement list. Use the current SDS for your grade for the complete, confirmed hazard classification before handling.
Regulatory & Compliance Notes
2,6-Dichlorofluorobenzene is a registered specialty halogenated aromatic. Because obligations differ by territory and use, and because transport classification for this specific compound needs confirmation against your own SDS, the notes below are orientation rather than legal advice.
- GHS classification. Classified as a skin and eye irritant with respiratory irritation potential (Signal word: Warning); the SDS for your grade carries the full, confirmed hazard statements.
- Chemical inventories. Listed on major chemical inventories; confirm REACH registration status for your specific supply chain.
- Dangerous goods transport. Confirm the UN number, transport class and packing group with your logistics/EHS team against your current SDS before shipping — we did not find a confirmed, compound-specific UN number in public sources at drafting time, and do not publish an unverified figure here.
- HS code. Commonly declared under the halogenated-benzene derivatives heading; confirm the exact tariff line with your customs broker for your jurisdiction.
