Chemical Structure

Terbufos-Sulfoxide CAS 10548-10-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Terbufos-Sulfoxide.

Terbufos-Sulfoxide (CAS 10548-10-4), molecular formula C9H21O3PS3 and molecular weight 304.43 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, Terbufos-Sulfoxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
