Chemical Structure

Trifenofos CAS 38524-82-2 chemical structure

Description

Trifenofos (CAS 38524-82-2) is a high-purity analytical reference standard with the molecular formula C11H14Cl3O3PS and a molecular weight of 363.62 g/mol.

The molecular framework of Trifenofos (C11H14Cl3O3PS) is characterized by a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
