Description
CATO manufactures 4’-Desmethyl-6’-tosylmycophenolic Acid 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.
4’-Desmethyl-6’-tosylmycophenolic Acid (CAS 171808-03-0), molecular formula C23H24O8S and molecular weight 460.50 g/mol, is a CATO reference standard with documented purity and traceability.
4’-Desmethyl-6’-tosylmycophenolic Acid (C23H24O8S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
