Description
Malathion-d10 (CAS 347841-48-9), molecular formula C10H9D10O6PS2 and molecular weight 340.42 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H9D10O6PS2, Malathion-d10 contains deuterium isotope labeling, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.42 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), Malathion-d10 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.
