Chemical Structure
Description
Warfarin Impurity 7 (CAS 67588-18-5), molecular formula C19H14O4 and molecular weight 306.31 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H14O4, Warfarin Impurity 7 contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 306.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Warfarin Impurity 7 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.
