Chemical Structure
Description
Sodium tetrahydropyransulfinate (CAS 1516140-99-0), molecular formula C5H9O3SNa and molecular weight 172.17 g/mol, is a CATO reference standard with documented purity and traceability.
Sodium tetrahydropyransulfinate (C5H9O3SNa) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Sodium tetrahydropyransulfinate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
