It is also sold as 3,4-DCNB, 1,2-Dichloro-4-nitrobenzene, 3,4-Dichloronitrobenzene. All refer to CAS 99-54-7. Confirm the CAS number with any supplier before ordering.

Price depends on grade, volume, packing, Incoterm and destination port, and moves with raw material markets. Send us your requirement and we will quote in EUR or USD with a landed-cost breakdown, usually within one business day.

3,4-Dichloro Nitro Benzene is a dichlorinated nitroaromatic used mainly to make 3,4-dichloroaniline for phenylurea and anilide herbicides, and as a halogen-exchange feed for fluoro-nitro intermediates..

Standard grade offers 98.5% minimum GC purity. Premium grade offers 99.5% minimum, lower water content and inert-gas blanketed packaging. Premium is recommended for multi-step routes with tight impurity control.

Its reduction product, 3,4-dichloroaniline, is used to build propanil and phenylurea herbicides such as diuron and linuron.

No. They are different isomers (99-54-7 and 3209-22-1) with different melting points and downstream uses. Confirm the CAS on the COA.

Store in closed containers in a cool, dry, ventilated place away from strong bases and reducing agents. 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). 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.
