Para Phenylenediamine: direct from source to Europe
Para Phenylenediamine (CAS 106-50-3) is a crystalline diamine used in polymer curing, fibre production, specialty dyes, pigments and rubber and fuel antioxidants. We supply it as an industrial chemical intermediate for these uses, not for cosmetic or hair-colour formulation.
- COA, SDS & TDS with every batch
- REACH status confirmed before quote
- Samples available for qualification
Para 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: Para Phenylenediamine, CAS 106-50-3.
- Confirmed CAS number on every COA
- Premium grade with HPLC purity 99%+ available
- TDS and SDS supplied with every shipment
⚠ Not the same as Ortho Phenylenediamine (95-54-5) or Meta Phenylenediamine (108-45-2). Always match CAS 106-50-3. PPD is a well-documented skin sensitiser; end use should be confirmed before order.
Para 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.
Para 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.
All values are specification limits, not guaranteed minima. Actual COA figures for your lot are provided before dispatch. Non-standard specifications are available on enquiry.

Para Phenylenediamine (CAS 106-50-3) is a crystalline diamine used in polymer curing, fibre production, specialty dyes, pigments and rubber and fuel antioxidants. We supply it as an industrial chemical intermediate for these uses, not for cosmetic or hair-colour formulation.
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 fibre and polymer routes needing consistent colour and low impurities.
No. We supply PPD as an industrial chemical intermediate, for uses such as polymer, fibre, rubber and pigment chemistry. It is a well-known skin sensitiser and is separately regulated for cosmetic use in the EU; if your application is cosmetic, tell us so we can advise on the correct regulatory pathway, which this supply does not cover.
Para Phenylenediamine is classified as a skin sensitiser and can face REACH, CLP and use-specific restrictions (including separate EU cosmetics regulation for hair-dye use, which this industrial supply does not cover). 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 and discolouration. 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.
