6-Hydroxychlorzoxazone- (CAS 475295-90-0), molecular formula C[13C]6H4ClNO3 and molecular weight 191.52 g/mol, is a CATO reference standard with documented purity and traceability.
6-Hydroxychlorzoxazone- (C[13C]6H4ClNO3) contains an amide group, a carboxylic acid group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 6-Hydroxychlorzoxazone- 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.
