4-[5-(4-Chlorobenzoyl)-1,3-thiazol-2-yl]-3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole CAS 338965-22-3

Description

Compared with other compounds in its class, the molecular weight of 449.74 g/mol gives 4-[5-(4-Chlorobenzoyl)-1,3-thiazol-2-yl]-3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-[5-(4-Chlorobenzoyl)-1,3-thiazol-2-yl]-3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole (CAS 338965-22-3), molecular formula C20H11Cl3N2O2S and molecular weight 449.74 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 4-[5-(4-Chlorobenzoyl)-1,3-thiazol-2-yl]-3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 449.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
