Synthesis, spectroscopic characterization and in vitro biological studies on azo colorants containing a 3-amino-6-bromopyridine nucleus

Four new heterocyclic azo dyes (D1–D4) were synthesized from 3-amino-6-bromopyridine via a diazo-coupling approach at 0–4 °C. Structural characterization using FT-IR, 1H NMR, ESI-MS, and UV-visible spectroscopy confirmed the formation of the target compounds with yields ranging from 68% to 81%. Elec...
