Chemical Structure

Potassium (methoxycarbonothioyl)sulfide CAS 34520-64-4 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 Potassium (methoxycarbonothioyl)sulfide.

Potassium (methoxycarbonothioyl)sulfide (CAS 34520-64-4) is a high-purity analytical reference standard with the molecular formula C2H3OS2K and a molecular weight of 146.26 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, Potassium (methoxycarbonothioyl)sulfide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.26 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.
