CATO manufactures 5-Acetyl-4-(thiophen-2-yl)pyrano[3,2-b]indol-2(5H)-one 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.
5-Acetyl-4-(thiophen-2-yl)pyrano[3,2-b]indol-2(5H)-one (CAS 2347639-48-7), molecular formula C17H11NO3S and molecular weight 309.34 g/mol, is a CATO reference standard with documented purity and traceability.
5-Acetyl-4-(thiophen-2-yl)pyrano[3,2-b]indol-2(5H)-one (C17H11NO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
