- TDS and SDS supplied with every shipment
⚠ Not the same as Meta Toluidine (108-44-1) or Para Toluidine (106-49-0). Always match CAS 95-53-4.
Ortho Toluidine 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 Toluidine 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.

Ortho Toluidine (CAS 95-53-4) is a pale yellow liquid, the ortho isomer of toluidine, and one of the most widely used amine intermediates for azo pigments and rubber chemicals.
Standard grade offers 99.0% minimum GC purity. Premium grade offers 99.5% minimum with lower isomer content and better colour. Premium is recommended for pigment synthesis routes needing consistent shade.
The three isomers differ in the position of the methyl group relative to the amine, and in physical form. Ortho (95-53-4) and meta (108-44-1) toluidine are liquids at room temperature, while para toluidine (106-49-0) is a solid melting near 44 °C. 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, protected from light and air, which promote darkening and oxidation. Use within the shelf life stated on the COA and TDS.
It is generally treated as a dangerous good for transport (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.
