Chemical Structure

Ethyl thioglycolate CAS 623-51-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 120.17 g/mol gives Ethyl thioglycolate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl thioglycolate (CAS 623-51-8), a certified reference material (molecular formula C4H8O2S, MW 120.17 g/mol) for analytical method development and quality control.

Structurally, Ethyl thioglycolate (C4H8O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 120.17 g/mol, it falls into the low-molecular-weight range.

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.

As a certified reference material (CRM), Ethyl thioglycolate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
