Description
CATO manufactures 5-(((4-Chlorobenzyl)thio)methyl)isoxazol-3(2H)-one 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.
CATO supplies 5-(((4-Chlorobenzyl)thio)methyl)isoxazol-3(2H)-one (CAS 89660-76-4), a certified reference material (molecular formula C11H10ClNO2S, MW 255.72 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H10ClNO2S, 5-(((4-Chlorobenzyl)thio)methyl)isoxazol-3(2H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 255.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
