Ortho Phenylene Diamine: 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: o-Phenylenediamine (1,2-Diaminobenzene), CAS 95-54-5.
⚠ Not the same as m-phenylenediamine (CAS 108-45-2) or p-phenylenediamine (CAS 106-50-3). Always match the CAS number before ordering.
Ortho Phenylene Diamine 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 Phenylene Diamine grade specifications: standard vs premium
We offer two grades of o-Phenylenediamine (1,2-Diaminobenzene). Your process chemist or quality team can pick the grade that 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 (tighter purity, custom impurity limits) are available on enquiry.
Where Ortho Phenylene Diamine is used
o-Phenylenediamine (1,2-Diaminobenzene) is a versatile building block in agrochemical, pharmaceutical, dye and specialty synthesis.
Benzimidazole fungicides
Raw material for carbendazim, thiabendazole and related actives.
Heterocycle synthesis
Building block for benzimidazoles, quinoxalines and benzotriazole.
Dyes & specialty chemicals
Used in dyes, polymer intermediates and corrosion inhibitors.
Custom & toll synthesis
Building block for contract research organisations and toll manufacturers developing proprietary routes.
R&D & laboratory
Lab and pilot samples with COA and SDS so your chemists can qualify the grade before scaling.
Formulation supply chains
Steady supply for European blenders and formulators that need consistent, repeatable lots.
Buyer's checklist for OPD in bulk
Sourcing o-Phenylenediamine (1,2-Diaminobenzene) for a European plant is more than comparing price per kg. Use this list to evaluate any supplier.
- Confirm CAS 95-54-5 and the isomer on the COA
- Request GC purity, water content, appearance and impurity profile
- Verify REACH status and who is importer of record for EU entry
- Compare landed cost by Incoterm: FOB, CFR, CIF or DAP
- Qualify a lab sample before committing to a full order
- Confirm dangerous-goods packing, CLP labelling and forwarder details

Four reasons European buyers trust Chelora
We take ownership of your supply chain from sourcing through to delivery. Here is what that means in practice.
Verified quality, every batch
Each lot ships with a batch-specific COA covering GC purity, water content and isomer confirmation, not a generic certificate.
EU-ready documentation
COA, EU-format SDS, TDS, bill of lading, dangerous-goods declaration, packing list, invoice and certificate of origin come as standard.
End-to-end logistics
We book freight through licensed DG forwarders, prepare customs papers and coordinate delivery to your port or plant.
REACH & regulatory support
We confirm REACH status before quoting and advise on importer-of-record arrangements for EU market entry.
Packed to your site, documented for customs
Ortho Phenylene Diamine is handled as a dangerous good. Every shipment leaves with UN-approved packaging, CLP labelling and the full document set for European import.
25 kg PE-lined bags
Palletised, stretch-wrapped bags for easy warehouse handling and manual charging.
25 kg net / bagFibre or HDPE drums
UN-approved drums with inner liner, suited to smaller lots and repeat call-offs.
Drum size on requestPalletised FCL loads
Full 20 ft container loads for contract buyers, with LCL available for trial orders.

Ortho Phenylene Diamine is an aromatic diamine used to make benzimidazole fungicides, heterocycles, dyes and corrosion inhibitors.
Standard grade offers 98.0% minimum GC purity. Premium grade offers 99.0% minimum GC purity, lower water content and inert-gas blanketed packaging to limit oxidative darkening. Premium is recommended for high-yield or multi-step routes with tight impurity control.
Keep it in tightly closed original UN-approved containers, away from light, moisture, heat, oxidisers and acids. Aromatic amines can darken on prolonged exposure to air, so use the material within the shelf life stated on the COA and TDS.
Yes. We supply laboratory and pilot-scale samples with a certificate of analysis and safety data sheet so your team can qualify the grade before scaling up. Ask about sample availability when you send your enquiry.
It is treated as a dangerous good (transport classification: UN 1673 (phenylenediamines), typically Class 6.1 toxic substances; 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 transport.
A standard shipment includes the bill of lading, commercial invoice, packing list, certificate of analysis, safety data sheet, dangerous-goods declaration and certificate of origin. Other certificates are available on request for applicable trade routes.
REACH status is confirmed before we quote. We work with customers on the appropriate importer-of-record arrangements and can advise whether the substance is registered for your intended use. Send us your use descriptor and we will confirm.
