Meta Nitrochlorobenzene
A chlorinated nitrobenzene supplied as a reduction feedstock and dye intermediate, converting cleanly to meta-chloroaniline for downstream synthesis.
What is Meta Nitrochlorobenzene?
Meta Nitrochlorobenzene is a pale yellow crystalline solid carrying a chlorine atom and a nitro group in the 1,3 (meta) relationship on a benzene ring.
That arrangement gives a nitro group that reduces cleanly to the corresponding amine while leaving the aryl chloride available for further substitution chemistry, which is why the compound is widely used as a dye intermediate en route to meta-chloroaniline and related building blocks for dye, pharmaceutical and agrochemical synthesis.
At Chelora Dyes, Meta Nitrochlorobenzene is crystallised and dried to a controlled particle profile and low moisture, so downstream reduction and coupling reactions run cleanly and give consistent, reproducible results batch to batch.

Handling precautions
Meta Nitrochlorobenzene is classified as toxic and a possible environmental hazard; contact and inhalation should be strictly avoided.
Use closed handling equipment, dust extraction, and full PPE including chemically resistant gloves, goggles and, where indicated by the risk assessment, respiratory protection during weighing, charging and any bulk handling operation.
Keep away from reducing agents, strong bases and sources of ignition.
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 Nitrochlorobenzene used for?
Meta Nitrochlorobenzene is used chiefly as a nitro intermediate that is reduced to meta-chloroaniline for further dye, pharmaceutical and agrochemical synthesis.
Why is this substitution pattern useful as an intermediate?
The meta relationship between the nitro group and the chlorine allows the nitro group to be reduced cleanly to the amine while the aryl chloride remains available for further substitution chemistry.
Is Meta Nitrochlorobenzene soluble in water?
It has very low water solubility and is more soluble in organic solvents such as alcohol, ether and benzene.
What purity do you supply?
Standard technical grade is supplied at a minimum assay of 98.5%, with moisture and melting range held within tight limits. Higher assay grades can be manufactured to order.
What packaging sizes are available?
25 kg and 50 kg multiwall paper or HDPE-lined bags, with bulk supply available in 500 kg and 1000 kg jumbo bags.
How should it be stored, and for how long?
In sealed original packaging in a cool, dry, ventilated store away from reducing agents and strong bases. Shelf life is 24 months from manufacture when storage conditions are maintained.
Is it hazardous to handle?
It is classified as toxic and a suspected environmental hazard and must be handled strictly according to its Safety Data Sheet, with closed handling, dedicated PPE and adequate ventilation.
Do you provide a Certificate of Analysis?
Yes. Each batch ships with a Certificate of Analysis and Safety Data Sheet covering assay, moisture, appearance and melting point.
