It is also sold as p-Nitrotoluene, 4-Nitrotoluene, 1-Methyl-4-nitrobenzene. All refer to CAS 99-99-0. 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.

Para Nitrotoluene (CAS 99-99-0) is a pale yellow crystalline solid, the para isomer of nitrotoluene, used as the principal intermediate for p-toluidine and downstream dyes, pigments and rubber chemicals.

Standard grade offers 98.0% minimum GC purity. Premium grade offers 99.0% minimum with lower isomer content and moisture. Premium is recommended for toluidine reduction routes needing tight impurity control.

The three isomers differ in the position of the nitro group relative to the methyl group. Para (99-99-0) gives p-toluidine on reduction, the intermediate for many rubber chemicals, while ortho (88-72-2) and meta (99-08-1) feed different pigment and dye routes. Order by CAS to get the isomer you need.

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 below 40 °C where possible, away from light, strong reducing agents and 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.
