Chemical Structure
Description
3-(4-Chlorophenyl)-5-[(phenylsulfanyl)methyl]-1,2-oxazole (CAS 478048-79-2), molecular formula C16H12ClNOS and molecular weight 301.79 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Chlorophenyl)-5-[(phenylsulfanyl)methyl]-1,2-oxazole (C16H12ClNOS) contains a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-(4-Chlorophenyl)-5-[(phenylsulfanyl)methyl]-1,2-oxazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
