Description
CATO manufactures 2-(tert-Butyl)benzo[d]oxazole-7-sulfonyl chloride 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.
2-(tert-Butyl)benzo[d]oxazole-7-sulfonyl chloride (CAS 914638-40-7) is a high-purity analytical reference standard with the molecular formula C11H12ClNO3S and a molecular weight of 273.74 g/mol.
2-(tert-Butyl)benzo[d]oxazole-7-sulfonyl chloride (C11H12ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. 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.
