It is also sold as m-Dichlorobenzene, 1,3-Dichlorobenzene, m-DCB, meta-Dichlorobenzol. All refer to CAS 541-73-1. 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.

Meta Dichloro Benzene is a chlorinated aromatic liquid used as an intermediate for agrochemicals, pharmaceuticals and dyes, and as a process solvent.

Standard grade offers 99.0% 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.

All three are C6H4Cl2. The meta isomer is 541-73-1, ortho is 95-50-1 and para is 106-46-7. Only the CAS and a GC isomer profile on the COA separate them reliably.

Commercial dichlorobenzene streams contain small amounts of the ortho and para isomers, which can carry into nitration products. Tell us your limits and we will confirm them on the COA.

Store in closed, labelled containers in a cool, ventilated area, away from strong oxidisers. 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.
