Chemical Structure

Malathion-d6 CAS 1189877-72-2 chemical structure

Description

The molecular framework of Malathion-d6 (C10H13D6O6PS2) is characterized by deuterium isotope labeling, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Malathion-d6 (CAS 1189877-72-2) is a high-purity analytical reference standard with the molecular formula C10H13D6O6PS2 and a molecular weight of 336.39 g/mol.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
