Chemical Structure

mercaptoacetaldehyde CAS 4124-63-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 76.12 g/mol gives mercaptoacetaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

mercaptoacetaldehyde (CAS 4124-63-4), molecular formula C2H4OS and molecular weight 76.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, mercaptoacetaldehyde is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 76.12 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.
