Chemical Structure
Description
CATO supplies 3-Ethyl-2-methylbenzo[d]thiazol-3-ium 4-methylbenzenesulfonate (CAS 14933-76-7), a certified reference material (molecular formula C10H12NSC7H7O3S, MW 349.46 g/mol) for analytical method development and quality control.
The molecular framework of 3-Ethyl-2-methylbenzo[d]thiazol-3-ium 4-methylbenzenesulfonate (C10H12NSC7H7O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
