Chemical Structure
Description
The occurrence of 4-Nitrobenzo[d]thiazole is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Nitrobenzo[d]thiazole (CAS 2942-08-7) is a high-purity analytical reference standard with the molecular formula C7H4N2O2S and a molecular weight of 180.18 g/mol.
4-Nitrobenzo[d]thiazole (C7H4N2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
