Compared with other compounds in its class, the molecular weight of 302.30 g/mol gives Malathion β-Monoacid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Malathion β-Monoacid (CAS 1642-51-9), a certified reference material (molecular formula C8H15O6PS2, MW 302.30 g/mol) for analytical method development and quality control.
The molecular framework of Malathion β-Monoacid (C8H15O6PS2) is characterized by a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
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), Malathion β-Monoacid 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.
