6-Chloro-2,4-Dinitroaniline (CAS 3958-71-2) is a crystalline chlorodinitroaromatic amine used as a diazo component for azo dyes and pigments, and as an intermediate in specialty colourant synthesis.

Standard grade offers 97.0% minimum HPLC purity. Premium grade offers 98.5% minimum with lower moisture and ash. Premium is recommended for dye and pigment routes needing consistent shade.

Like other dinitroaromatics, it should be kept away from heat, ignition sources and strong reducing agents, and handled per the current SDS. We confirm any transport desensitisation or wetting requirements before shipment. Order by CAS (3958-71-2).

Aromatic amines can face REACH, CLP and workplace-exposure obligations depending on use. We confirm the current status for your application before quoting.

Store in closed containers in a cool, dry, ventilated place, away from heat, ignition sources, strong oxidisers, reducing agents and bases. Use within the shelf life stated on the COA and TDS.

It is treated as a dangerous good (class and UN number per SDS; always confirm on the current SDS, including any requirement to ship the material wetted or desensitised). We pack it in UN-approved containers, apply CLP labels and ship through licensed forwarders under IMDG for sea and ADR for European road.

Yes. Laboratory and pilot samples are supplied with a COA and SDS so your team can qualify the grade. Mention sample needs in your enquiry.

REACH status is confirmed before we quote. We advise on importer-of-record arrangements and whether the substance is registered for your use. Send your use descriptor and we will confirm.
