Chemical Structure
Description
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.
CATO supplies 3-(6-Chlorobenzo[d]thiazol-2-yl)-1-(2,4-dichlorobenzyl)pyridin-2(1H)-one (CAS 400075-86-7), a certified reference material (molecular formula C19H11Cl3N2OS, MW 421.73 g/mol) for analytical method development and quality control.
The molecular framework of 3-(6-Chlorobenzo[d]thiazol-2-yl)-1-(2,4-dichlorobenzyl)pyridin-2(1H)-one (C19H11Cl3N2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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 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).
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.
