Synthesis and characterization of novel furoate azodye using spectral and thermal methods of analysis

Abstract

A new azoester, 4-(4-chloro-phenyldiazenyl)-2,6-dimethyl-phenyl 2-furoate (CPPF), has been synthesized by condensing 4-(4-chloro-phenylazo)-2,6-dimethyl-phenol with 2-furoyl chloride in pyridine. This compound has been characterized by elemental analysis (C, H, N), FTIR, UV–Vis, NMR (1H and 13C), and thermal analysis studies. Spectral analysis results confirmed the structure of the compound synthesized. Thermal analysis established that CPPF is stable up to 260 °C; melts at about 178 °C; and between 260 and 450 °C, it decomposes in two steps.
