5-((4-Chlorophenyl)thio)-4-(4-methoxyphenyl)-2-phenylthiazole CAS 865658-08-8

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 5-((4-Chlorophenyl)thio)-4-(4-methoxyphenyl)-2-phenylthiazole (CAS 865658-08-8), a certified reference material (molecular formula C22H16ClNOS2, MW 409.95 g/mol) for analytical method development and quality control.

5-((4-Chlorophenyl)thio)-4-(4-methoxyphenyl)-2-phenylthiazole (C22H16ClNOS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
