Description
CATO supplies Quinine Sulfate - Impurity C (Sulfate Salt) (CAS 49722-46-5), a certified reference material (molecular formula C20H26N2O2H2O4S, MW 424.51 g/mol) for analytical method development and quality control.
The molecular framework of Quinine Sulfate - Impurity C (Sulfate Salt) (C20H26N2O2H2O4S) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Quinine Sulfate - Impurity C (Sulfate Salt) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
