4-[2-(2-Chlorophenyl)-1,3-thiazol-4-yl]-5-methyl-1,2-oxazole CAS 478049-20-6

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.

4-[2-(2-Chlorophenyl)-1,3-thiazol-4-yl]-5-methyl-1,2-oxazole (CAS 478049-20-6) is a high-purity analytical reference standard with the molecular formula C13H9ClN2OS and a molecular weight of 276.74 g/mol.

The molecular framework of 4-[2-(2-Chlorophenyl)-1,3-thiazol-4-yl]-5-methyl-1,2-oxazole (C13H9ClN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
