It is also sold as Chlorobenzene, MCB, Phenyl chloride. All refer to CAS 108-90-7. 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.

Mono Chlorobenzene (CAS 108-90-7) is a clear, colourless liquid used as a solvent and as the principal intermediate for nitrochlorobenzenes, phenol, and a wide range of agrochemical and dye intermediates.

Standard grade offers 99.5% minimum GC purity. Premium grade offers 99.8% minimum with lower moisture, isomer content and colour. Premium is recommended for nitration routes needing tight impurity control.

No. Mono Chlorobenzene (108-90-7) carries a single chlorine atom, while ortho- (95-50-1) and meta-dichlorobenzene (541-73-1) carry two. This changes boiling point, density and downstream reactivity. Order by CAS to get the compound you need.

Chlorobenzene can face REACH and other restrictions depending on use. We confirm the current status for your application before quoting.

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

It is treated as a flammable dangerous good (Class 3, UN 1134; 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.
