Description
As a certified reference material (CRM), 6-Tosyl-2-oxa-6-azaspiro[3.3]heptane 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.
6-Tosyl-2-oxa-6-azaspiro[3.3]heptane (CAS 13573-28-9) is a high-purity analytical reference standard with the molecular formula C12H15NO3S and a molecular weight of 253.32 g/mol.
6-Tosyl-2-oxa-6-azaspiro[3.3]heptane (C12H15NO3S) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
