Chemical Structure
Description
As a certified reference material (CRM), 4-(3,4-Dimethylphenoxy)butane-1-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 4-(3,4-Dimethylphenoxy)butane-1-sulfonyl chloride (CAS 1342544-88-0), a certified reference material (molecular formula C12H17ClO3S, MW 276.78 g/mol) for analytical method development and quality control.
4-(3,4-Dimethylphenoxy)butane-1-sulfonyl chloride (C12H17ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. 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.
