2-[(4-Chloronaphthalen-1-yl)oxy]-1-(4-methyl-2-phenyl-1,3-thiazol-5-yl)ethan-1-one (CAS 478047-43-7), molecular formula C22H16ClNO2S and molecular weight 393.89 g/mol, is a CATO reference standard with documented purity and traceability.
2-[(4-Chloronaphthalen-1-yl)oxy]-1-(4-methyl-2-phenyl-1,3-thiazol-5-yl)ethan-1-one (C22H16ClNO2S) contains a steroid core, an amide group, a sulfone group, 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, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 2-[(4-Chloronaphthalen-1-yl)oxy]-1-(4-methyl-2-phenyl-1,3-thiazol-5-yl)ethan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
