Ortho Phenylenediamine: names, synonyms and identifiers
Buyers search for this material under several names. Whichever one appears on your specification, purchase order or REACH dossier, it is the same compound: Ortho Phenylenediamine, CAS 95-54-5.
- Confirmed CAS number on every COA
- Premium grade with HPLC purity 99%+ available
- TDS and SDS supplied with every shipment
⚠ Not the same as Meta Phenylenediamine (108-45-2) or Para Phenylenediamine (106-50-3). Always match CAS 95-54-5.
Ortho Phenylenediamine physical and chemical properties
Key parameters for process engineering, safety planning and storage design. Values are typical; always verify against the current TDS for your lot.
Ortho Phenylenediamine grade specifications: standard vs premium
Two grades are offered so your process chemist or quality team can pick what suits downstream requirements. COA parameters are confirmed before every shipment.

It is also sold as o-Phenylenediamine, 1,2-Diaminobenzene, o-PDA. All refer to CAS 95-54-5. 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.
Ortho Phenylenediamine (CAS 95-54-5) is a crystalline diamine and the key intermediate for benzimidazole-ring agrochemical and pharmaceutical actives, including carbendazim-type fungicides.
Standard grade offers 98.0% minimum HPLC purity. Premium grade offers 99.0% minimum with lower moisture and better melt colour. Premium is recommended for benzimidazole synthesis routes needing tight impurity control.
All three are diaminobenzene isomers but serve different industries. Ortho (95-54-5) is the benzimidazole fungicide intermediate, meta (108-45-2) is used mainly as an epoxy curing agent and aramid fibre monomer, and para (106-50-3) is used in polymers, dyes and hair-colour chemistry. Order by CAS to get the isomer you need.
Phenylenediamines are skin sensitisers and can face REACH, CLP and workplace-exposure obligations depending on use. We confirm the current status for your application before quoting.
Store tightly sealed in a cool, dry place, ideally under inert gas, away from light, air and oxidisers, which cause rapid darkening. 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.
