Ortho Nitro Chloro Benzene is the ortho isomer of chloronitrobenzene.
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.
It melts around 32 °C, so it may arrive as solid, partially molten or fully molten in warm transit. Warm gently and homogenise before sampling or charging.
Nitration of chlorobenzene gives both isomers, and the split, separation cost and market demand for each set the relative prices. Ask for both when comparing.
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.
