Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,3-Dimethyl-Azetidine 4-methylbenzenesulfonate (1:1) (CAS 91554-85-7), molecular formula C7H8O3SC5H11N and molecular weight 257.35 g/mol, is a CATO reference standard with documented purity and traceability.
3,3-Dimethyl-Azetidine 4-methylbenzenesulfonate (1:1) (C7H8O3SC5H11N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
As a certified reference material (CRM), 3,3-Dimethyl-Azetidine 4-methylbenzenesulfonate (1:1) 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.
