It is also sold as N,N-Diethylbenzenamine, Diethylaniline, DEA (aniline). All refer to CAS 91-66-7. 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-Diethylaniline (CAS 91-66-7) is a colourless to pale yellow liquid tertiary aromatic amine used as a coupling component for dyes and pigments, an acid scavenger in synthesis, and an intermediate for specialty chemicals.
Standard grade offers 98.0% minimum GC purity. Premium grade offers 99.0% minimum with lower moisture and better colour. Premium is recommended for dye coupling routes needing consistent shade.
N,N-Diethylaniline (91-66-7) carries two ethyl groups on nitrogen, while N,N-Dimethylaniline (121-69-7) carries two methyl groups. The longer ethyl chains change boiling point, basicity and the shade obtained in coupling reactions. Order by CAS to get the compound 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.
