Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Quinine Sulfate (500 mg) (CAS 207671-44-1), molecular formula C20H24N2O2H2O4SH2O and molecular weight 440.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Quinine Sulfate (500 mg) (C20H24N2O2H2O4SH2O) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Quinine Sulfate (500 mg) 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.
