Chemical Structure
Description
The molecular framework of Chlorpyrifos Impurity 6 (C6H15O3PS) is characterized by a sulfone group, a phosphonate 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.
CATO supplies Chlorpyrifos Impurity 6 (CAS 4486-44-6), a certified reference material (molecular formula C6H15O3PS, MW 198.22 g/mol) for analytical method development and quality control.
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), Chlorpyrifos Impurity 6 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.
