Description
Ochratoxin A-d5 (CAS 666236-28-8), molecular formula C20H13D5ClNO6 and molecular weight 408.84 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H13D5ClNO6, Ochratoxin A-d5 contains deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 408.84 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).
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), Ochratoxin A-d5 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.
