Chemical Structure

S-(1-Ethoxyethyl) ethanethioate CAS 78872-75-0 chemical structure

Description

S-(1-Ethoxyethyl) ethanethioate (CAS 78872-75-0), molecular formula C6H12O2S and molecular weight 148.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, S-(1-Ethoxyethyl) ethanethioate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.22 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.
