Chemical Structure

Dioxathion CAS 78-34-2 chemical structure

Description

Based on its molecular formula C12H26O6P2S4, Dioxathion contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 456.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

Dioxathion (CAS 78-34-2), molecular formula C12H26O6P2S4 and molecular weight 456.54 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.

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.
