Chemical Structure

iso-Malathion CAS 3344-12-5 chemical structure

Description

iso-Malathion (CAS 3344-12-5), molecular formula C10H19O6PS2 and molecular weight 330.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H19O6PS2, iso-Malathion contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 330.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

As a certified reference material (CRM), iso-Malathion 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.
