Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 251.30 g/mol gives Carboxin Sulfoxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Carboxin Sulfoxide (CAS 17757-70-9), molecular formula C12H13NO3S and molecular weight 251.30 g/mol, is a CATO reference standard with documented purity and traceability.
Carboxin Sulfoxide (C12H13NO3S) 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.
As a certified reference material (CRM), Carboxin Sulfoxide 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.
