2-[(2,4-Dichlorophenyl)sulfanyl]-1-(4-methyl-2-phenyl-1,3-thiazol-5-yl)ethan-1-one CAS 478047-39-1

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.

2-[(2,4-Dichlorophenyl)sulfanyl]-1-(4-methyl-2-phenyl-1,3-thiazol-5-yl)ethan-1-one (CAS 478047-39-1) is a high-purity analytical reference standard with the molecular formula C18H13Cl2NOS2 and a molecular weight of 394.34 g/mol.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 2-[(2,4-Dichlorophenyl)sulfanyl]-1-(4-methyl-2-phenyl-1,3-thiazol-5-yl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
