General description
4-Nitrobenzoyl chloride is a derivatization reagent. It reacts with L-glutamic acid undergoing methylation using formaldehyde, synthesizing N-(4-methylaminobenzoyl)glutaminic acid.
Application
4-Nitrobenzoyl chloride was used in separating polyhydric alcohols using HPLC. It was used in snythesizing cellulose benzotates by adding to cellulose/1-allyl-3-methylimidazolium chloride followed by characterization using FT-IF, 1H-NMR and 13C-NMR spectroscopy. It may be used in synthesizing 1-aryloxyacetyl-4-(4-nitrobenzoyl)-thiosemicarbazides under phase transfer catalysis and microwave irradiation with ammonium thiocyanate and aryloxyacetic acid hydrazides.
