Product Overview

4-Aminoazobenzene 98% For Synthesis (CAS No. 60-09-3) is an aromatic azo compound consisting of an azobenzene chromophore bearing a primary amino group in the para position. Conjugation across the phenyl rings and azo linkage gives the molecule its characteristic chromophoric behaviour, while the amino functionality provides a reactive site for diazotisation, condensation, acylation, and other derivatisation reactions. This combination makes 4-aminoazobenzene a versatile intermediate for extending conjugated structures and preparing functional azo compounds.

The Synthesis grade is intended for preparative organic chemistry, dye-intermediate research, and the development of amino-functionalised azobenzene derivatives. It is suitable for reaction sequences involving modification of the para-amino group, formation of additional azo linkages, preparation of Schiff bases, and synthesis of conjugated compounds for chemical and materials-related investigations.

Typical Applications

• Intermediate for the synthesis of azo, diazo, and related colour-forming compounds
• Diazotisation followed by coupling to prepare disazo and extended azo structures
• Preparation of selected acid-yellow and induline-type dye intermediates
• Condensation with suitable aldehydes to produce azobenzene-containing Schiff bases
• Synthesis of ligands and coordination compounds derived from aminoazobenzene structures
• Functionalisation of the para-amino group to prepare substituted azo derivatives
• Research involving azo chromophores and conjugated aromatic compounds
• Preparative organic-chemistry studies requiring an amino-functionalised azobenzene building block

4-Aminoazobenzene is recognised as a dye intermediate and chemical building block, while published synthetic work documents its use in diazotisation–coupling sequences and Schiff-base preparation.
