Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Pyrithioxin dihydrochloride (CAS 10049-83-9), molecular formula C16H20N2O4S2HCl and molecular weight 404.92 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H20N2O4S2HCl, Pyrithioxin dihydrochloride contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 404.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Pyrithioxin dihydrochloride 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.
