Chemical Structure

Fenthion-Sulfoxide CAS 3761-41-9 chemical structure

Description

Fenthion-Sulfoxide (CAS 3761-41-9) is a high-purity analytical reference standard with the molecular formula C10H15O4PS2 and a molecular weight of 294.33 g/mol.

The molecular framework of Fenthion-Sulfoxide (C10H15O4PS2) 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 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Fenthion-Sulfoxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
