Description
rac-Clopidogrel Acid N-Oxide (CAS CATO-C4X-102947), molecular formula C15H14ClNO3S and molecular weight 323.79 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H14ClNO3S, rac-Clopidogrel Acid N-Oxide contains a nitrogen-containing heterocyclic scaffold, 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 323.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), rac-Clopidogrel Acid N-Oxide 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.
