Chemical Structure

Ethyl (2-Oxo-1,3-benzothiazol-3(2{h})-yl)acetate CAS 951-41-7 chemical structure

Description

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.

CATO supplies Ethyl (2-Oxo-1,3-benzothiazol-3(2{h})-yl)acetate (CAS 951-41-7), a certified reference material (molecular formula C11H11NO3S, MW 237.27 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H11NO3S, Ethyl (2-Oxo-1,3-benzothiazol-3(2{h})-yl)acetate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 237.27 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.
