Chemical Structure
Description
Fenamiphos-Sulfoxide (CAS 31972-43-7), molecular formula C13H22NO4PS and molecular weight 319.36 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H22NO4PS, Fenamiphos-Sulfoxide contains an amide group, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 319.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Fenamiphos-Sulfoxide 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.
