Chemical Structure
Description
4-Phenyltetrahydro-2h-thiopyran-4-carboxylic acid 1,1-dioxide (CAS 873383-88-1), molecular formula C12H14O4S and molecular weight 254.30 g/mol, is a CATO reference standard with documented purity and traceability.
4-Phenyltetrahydro-2h-thiopyran-4-carboxylic acid 1,1-dioxide (C12H14O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
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 4-Phenyltetrahydro-2h-thiopyran-4-carboxylic acid 1,1-dioxide 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.
