It is also sold as p-Nitrophenol, 4-Nitrophenol, PNP. All refer to CAS 100-02-7. 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.

Para Nitrophenol (CAS 100-02-7) is a pale yellow crystalline solid, the para isomer of nitrophenol, used as a key intermediate for paracetamol (acetaminophen), dyes, pigments and organophosphate pesticide chemistry.

Standard grade offers 99.0% minimum HPLC purity. Premium grade offers 99.5% minimum with lower ortho-isomer content and moisture. Premium is recommended for pharmaceutical intermediate routes needing tight impurity control.

Both are mononitrophenol isomers, but they differ markedly in physical form and use. Para Nitrophenol (100-02-7) is a solid melting near 114 °C and is the isomer used for paracetamol synthesis, while Ortho Nitrophenol (88-75-5) is a lower-melting solid used in different dye and pesticide routes. Order by CAS.

Nitrophenols can face REACH, CLP and environmental restrictions depending on use. We confirm the current status for your application before quoting.

Store in closed containers in a cool, dry, ventilated place, away from light and 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.
