N-Ethyl-N-cyanoethyl-m-toluidine

N-Ethyl-N-cyanoethyl-m-toluidine has molecular formula C12H16N2, molecular weight 188.27 and CAS number 148-69-6. It is a light yellow to brown transparent liquid at room temperature with an assay (GC) of ≥98.0%, a boiling point of 312.8-362.8°C, a refractive index of 1.5470 and a pKa of 4.92-5.92 (see specifications). Compared with N-ethyl-N-cyanoethylaniline (CAS 148-87-8, molecular formula C11H14N2), this product carries one additional methyl group at the 3-position of the ring: the electron-donating effect of the methyl group acts on the conjugated system and shifts the dye shade toward red (finished-dye performance is subject to testing of the finished dye). The product is used mainly as a coupling component for orange and red disperse dyes for polyester fiber dyeing.

Used in dyes and fine chemicals as an important intermediate for synthesizing disperse dyes. Compared with N-ethyl-N-cyanoethylaniline, the methyl substituent on the m-toluidine scaffold serves to modulate dye shade and dyeing performance (finished-dye performance is subject to testing of the finished dye). Used primarily as a coupling component for orange and red disperse dye varieties for polyester fiber dyeing. The electron-donating effect of the methyl group acts on the conjugated system, shifting the dye shade toward red (finished-dye performance is subject to testing of the finished dye).

Used mainly as a coupling component for orange and red disperse dyes for polyester fiber dyeing; figures such as assay (GC ≥98.0%) and impurities N-ethyl-m-toluidine (≤1.0%) and N,N-diethyl-m-toluidine (≤0.5%) are listed under specifications for item-by-item review before charging. Specific routes follow the customer's process.

The electron-donating effect of the methyl group acts on the conjugated system and shifts the dye shade toward red; shade orientation depends on the specific dye structure and process, with finished-dye performance subject to testing of the finished dye.

Compared with N-ethyl-N-cyanoethylaniline (CAS 148-87-8), this product carries one additional 3-position methyl group, used to modulate dye shade and dyeing performance; the two are selected according to the target dye structure, and batch data can be confirmed with our sales team during inquiry.
