Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 246.75 g/mol gives 5-Tert-butyl-2-methylbenzene-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Tert-butyl-2-methylbenzene-1-sulfonyl chloride (CAS 63452-62-0), a certified reference material (molecular formula C11H15ClO2S, MW 246.75 g/mol) for analytical method development and quality control.
5-Tert-butyl-2-methylbenzene-1-sulfonyl chloride (C11H15ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
CATO manufactures 5-Tert-butyl-2-methylbenzene-1-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.
