It is also sold as N,N-Dimethylbenzenamine, Dimethylaniline, DMA (aniline). All refer to CAS 121-69-7. 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.

N,N-Dimethylaniline (CAS 121-69-7) is a colourless to pale yellow liquid tertiary aromatic amine, widely used as a coupling component for dyes and pigments, an accelerator in resin curing, and an intermediate for pharmaceuticals and rubber chemicals.

Standard grade offers 99.0% minimum GC purity. Premium grade offers 99.5% minimum with lower moisture and better colour. Premium is recommended for resin-accelerator and dye coupling routes needing consistent quality.

N,N-Dimethylaniline (121-69-7) carries two methyl groups on nitrogen, while N,N-Diethylaniline (91-66-7) carries two ethyl groups. The shorter methyl groups give higher reactivity and a different boiling point, so the two are not interchangeable in coupling and accelerator chemistry. Order by CAS.

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.
