Chemical Structure

6-Ethoxybenzo[d]thiazole-2-sulfonyl chloride CAS 1203923-23-2 chemical structure

Description

The occurrence of 6-Ethoxybenzo[d]thiazole-2-sulfonyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6-Ethoxybenzo[d]thiazole-2-sulfonyl chloride (CAS 1203923-23-2), a certified reference material (molecular formula C9H8ClNO3S2, MW 277.75 g/mol) for analytical method development and quality control.

Structurally, 6-Ethoxybenzo[d]thiazole-2-sulfonyl chloride (C9H8ClNO3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 277.75 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
