Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies Malathion α-Monoacid-d5 (CAS 1794980-03-2), a certified reference material (molecular formula C8H10D5O6PS2, MW 307.34 g/mol) for analytical method development and quality control.
Malathion α-Monoacid-d5 (C8H10D5O6PS2) 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. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Malathion α-Monoacid-d5 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
