Chemical Structure

<I>O</I>-isopropylxanthate potassium salt CAS 140-92-1 chemical structure

Description

The occurrence of <I>O</I>-isopropylxanthate potassium salt is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

<I>O</I>-isopropylxanthate potassium salt (CAS 140-92-1) is a high-purity analytical reference standard with the molecular formula C4H7KOS2 and a molecular weight of 174.33 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, <I>O</I>-isopropylxanthate potassium salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.33 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.
