N,N-Dicyanoethylaniline

N,N-Dicyanoethylaniline, also known as N,N-bis(2-cyanoethyl)aniline or 3,3'-(phenylimino)dipropionitrile, has molecular formula C12H13N3, molecular weight 199.26 and CAS number 1555-66-4. It appears as a light beige to light yellow solid with an assay (GC) of ≥96.0%, a melting point of 80-88°C, moisture ≤0.5% and residue on ignition ≤0.1% (see specifications). Nitrogen carries two cyanoethyl groups, which can undergo hydrolysis (yielding carboxylic acids), reduction (yielding amines) or cyclization separately or together — one more reaction site than mono-cyanoethyl intermediates such as N-cyanoethylaniline (CAS 1075-76-9) — making it a common raw material for building nitrogen-containing heterocyclic structures. Boiling point (412°C), flash point (189°C) and density (1.105 g/cm³) are likewise covered by the specifications. The product is supplied in 500 kg FIBC packaging for cationic dye, disperse dye and fine chemical synthesis.

Used in dyes, plastics and fine chemicals as an important intermediate for synthesizing cationic and disperse dyes. The two cyanoethyl groups on the nitrogen atom provide rich reaction sites for hydrolysis (yielding carboxylic acids), reduction (yielding amines) or cyclization, enabling construction of various nitrogen-containing heterocyclic structures. It serves as one of the scaffold intermediates in cationic and basic dye synthesis, and has applications in high-molecular-weight polymers and functional polymer preparation.

Serves as one of the scaffold intermediates in cationic and basic dye synthesis; pre-charge verification focuses on figures such as assay (GC ≥96.0%) and melting point (80-88°C) (see specifications), and batch data can be confirmed with our sales team during inquiry. Specific routes follow the customer's process.

The two cyanoethyl groups on nitrogen can undergo hydrolysis (yielding carboxylic acids), reduction (yielding amines) or cyclization separately or together, enabling construction of various nitrogen-containing heterocyclic structures; reaction conditions follow published methods and the customer's process validation.

In the plastics and fine chemical industries it is used in directions involving polymer materials and functional polymer preparation; this direction operates at the synthesis-route level, subject to the customer's process validation.
