Chemical Structure

4-(1,3-Benzothiazol-2-yl)benzoyl chloride CAS 2182-79-8 chemical structure

Description

The occurrence of 4-(1,3-Benzothiazol-2-yl)benzoyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(1,3-Benzothiazol-2-yl)benzoyl chloride (CAS 2182-79-8) is a high-purity analytical reference standard with the molecular formula C14H8ClNOS and a molecular weight of 273.74 g/mol.

Based on its molecular formula C14H8ClNOS, 4-(1,3-Benzothiazol-2-yl)benzoyl chloride contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 273.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
