Fenitrothion D6 (O,O-dimethyl D6) CAS 203645-59-4

Description

The molecular framework of Fenitrothion D6 (O,O-dimethyl D6) (C9H6D6NO5PS) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

Fenitrothion D6 (O,O-dimethyl D6) (CAS 203645-59-4), molecular formula C9H6D6NO5PS and molecular weight 283.27 g/mol, is a CATO reference standard with documented purity and traceability.

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), Fenitrothion D6 (O,O-dimethyl D6) 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.
