N-Cyanoethyl-N-benzylaniline

N-Cyanoethyl-N-benzylaniline has molecular formula C16H16N2, molecular weight 236.31 and CAS number 26322-20-3. It appears as light yellow crystals with an assay (GC) of ≥94%, a melting point of 102-103°C and a solid content of ≥85% (see specifications). Nitrogen carries both a benzyl and a cyanoethyl group: the benzyl group provides steric hindrance and hydrophobicity, while the cyanoethyl group retains reactivity for subsequent steps — a combination that makes this product a coupling component for azo disperse dyes, used in varieties such as Disperse Orange 73 and Disperse Orange 288 (prepared by diazotization of p-nitroaniline followed by coupling with this intermediate; variety correspondence follows the customer's synthesis route). Impurities are controlled separately as mono-cyano (≤3.5%) and di-benzyl (≤2%) (see specifications) and can be reviewed before charging.

Used in dyes and fine chemicals as an important coupling component for synthesizing disperse dyes. The benzyl group on nitrogen provides significant steric hindrance and hydrophobicity, while the cyanoethyl group offers subsequent reactivity. Used primarily for synthesizing disperse dye varieties such as Disperse Orange 73 and Disperse Orange 288 (prepared by diazotization of p-nitroaniline followed by coupling with this intermediate). This intermediate is common in azo disperse dye structures and is used in the industry for high-temperature high-pressure and thermosol dyeing of polyester fibers; the fastness performance of dyes of this structure is subject to the finished dye's test data.

Used mainly in azo disperse dye synthesis as a coupling component that couples with diazonium salts to build the dye molecule; varieties such as Disperse Orange 73 and Disperse Orange 288 are prepared by diazotization of p-nitroaniline followed by coupling with this intermediate; variety correspondence follows the customer's synthesis route. Specification review and batch data for the coupling component can be confirmed with our sales team during inquiry, and specific routes follow the customer's process.

The benzyl group on nitrogen provides substantial steric hindrance and hydrophobicity, a common substitution approach in disperse dye molecular design; the performance of dyes in this structural direction is subject to testing data of the finished dye.

Azo disperse dyes synthesized with this family of intermediates are used in the industry for high-temperature high-pressure and thermosol dyeing of polyester fibers; dyeing formulations and process conditions follow the finished dye's instructions and validation in the customer's own system.
