Mono Chlorobenzene
A single-chlorine aromatic liquid used as a solvent and as a foundational building block for dye, agrochemical and specialty chemical manufacture.
What is Mono Chlorobenzene?
Mono Chlorobenzene is a colourless, mobile liquid consisting of a benzene ring carrying a single chlorine substituent.
Its single, well-defined reactive site makes it one of the most versatile aromatic building blocks in industrial chemistry: the aryl chloride can be nitrated, aminated or otherwise functionalised to open routes into nitrochlorobenzenes, anilines and a wide range of dye, agrochemical and specialty chemical intermediates, while the liquid itself also serves as a stable, high-boiling process solvent.
At Chelora Dyes, Mono Chlorobenzene is distilled and quality-checked to a controlled purity and low moisture level, so downstream functionalisation and solvent applications run cleanly and give consistent, reproducible results batch to batch.

- Re-seal drums promptly after use to preserve purity specification.
Handling precautions
Mono Chlorobenzene is classified as flammable and harmful; 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, open flame and other ignition sources.
Refer to the full Safety Data Sheet for exposure limits, spill containment, disposal, and first-aid measures before use.
Frequently asked questions
What is Mono Chlorobenzene used for?
Mono Chlorobenzene is used as an aromatic building block that is nitrated or otherwise functionalised into dye, agrochemical and pharmaceutical intermediates, and as a process solvent.
Why is it considered such a versatile building block?
Its single, well-defined aryl chloride site can be nitrated, aminated or further substituted, opening routes to a wide range of downstream aromatic intermediates from one starting material.
Is Mono Chlorobenzene 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 99.5%, 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 ignition sources. Shelf life is 24 months from manufacture when storage conditions are maintained.
Is it hazardous to handle?
It is classified as flammable and harmful 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.
