2-((4-Chlorophenyl)thio)-1-(4-methyl-2-phenylthiazol-5-yl)ethan-1-one CAS 478047-38-0

Description

2-((4-Chlorophenyl)thio)-1-(4-methyl-2-phenylthiazol-5-yl)ethan-1-one (CAS 478047-38-0), molecular formula C18H14ClNOS2 and molecular weight 359.89 g/mol, is a CATO reference standard with documented purity and traceability.

2-((4-Chlorophenyl)thio)-1-(4-methyl-2-phenylthiazol-5-yl)ethan-1-one (C18H14ClNOS2) 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. 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.
