Meta Dichlorobenzene
A colourless, symmetrically chlorinated benzene liquid used as a solvent and as a versatile intermediate across dye, agrochemical and specialty chemical manufacture.
What is Meta Dichlorobenzene?
Meta Dichlorobenzene is a colourless liquid built on a benzene ring carrying two chlorine atoms in the 1,3 (meta) relationship.
Its balanced chlorine substitution gives the molecule good chemical and thermal stability along with broad miscibility with organic solvents, which is why it functions well both as a process solvent and as a building block that is further functionalised into herbicide, dye and specialty chemical intermediates.
At Chelora Dyes, Meta Dichlorobenzene is distilled and quality-checked to a controlled purity and low moisture level, so downstream reactions and solvent applications run cleanly and give consistent, reproducible results batch to batch.

Storage and guidelines
- Store in tightly sealed original drums or IBCs in a dry environment.
- Keep in a cool, well-ventilated area away from direct sunlight and open flame.
- Segregate strictly from strong oxidising agents.
- Keep containers upright and check seals regularly to prevent evaporative loss.

- Re-seal drums promptly after use to preserve purity specification.
Handling precautions
Meta Dichlorobenzene is classified as harmful and a possible environmental hazard; prolonged contact and inhalation of vapour should be avoided.
Use adequate ventilation, vapour extraction where handled in volume, and PPE including chemically resistant gloves and goggles during transfer and bulk handling operations.
Keep away from strong oxidisers and open flame; vapours may form flammable mixtures with air at elevated temperature.
Refer to the full Safety Data Sheet for exposure limits, spill containment, disposal, and first-aid measures before use.
Frequently asked questions
What is Meta Dichlorobenzene used for?
Meta Dichlorobenzene is used as a process solvent and as an intermediate that is further functionalised into herbicide, dye and specialty chemical actives.
Why is the meta (1,3) substitution pattern useful?
The symmetrical placement of the two chlorine atoms gives the molecule good stability and broad solvency, supporting consistent performance as both a solvent and a reaction intermediate.
Is Meta Dichlorobenzene soluble in water?
It is practically insoluble in water but is miscible with alcohol, ether and most common organic solvents.
What purity do you supply?
Standard technical grade is supplied at a minimum assay of 99%, with moisture held within tight limits. Higher assay grades can be manufactured to order.
What packaging sizes are available?
170–200 kg drums as standard, with IBC and bulk tanker supply available on request.
How should it be stored, and for how long?
In sealed original drums in a cool, ventilated store away from strong oxidisers and open flame. Shelf life is 24 months from manufacture when storage conditions are maintained.
Is it hazardous to handle?
It is classified as harmful and a suspected environmental hazard and must be handled according to its Safety Data Sheet, with adequate ventilation and appropriate PPE.
Do you provide a Certificate of Analysis?
Yes. Each batch ships with a Certificate of Analysis and Safety Data Sheet covering assay, moisture and appearance.
