Chemical Structure
Description
As a certified reference material (CRM), 3-(4-Chloro-2,5-dimethylbenzenesulfonyl)-4,6-dimethyl-2-(2-methylpropoxy)pyridine 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.
3-(4-Chloro-2,5-dimethylbenzenesulfonyl)-4,6-dimethyl-2-(2-methylpropoxy)pyridine (CAS 400078-20-8), molecular formula C19H24ClNO3S and molecular weight 381.92 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Chloro-2,5-dimethylbenzenesulfonyl)-4,6-dimethyl-2-(2-methylpropoxy)pyridine (C19H24ClNO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
