Chemical Structure

ethyl 3-sulfanylbutanoate CAS 156472-94-5 chemical structure

Description

ethyl 3-sulfanylbutanoate (CAS 156472-94-5) is a high-purity analytical reference standard with the molecular formula C6H12O2S and a molecular weight of 148.22 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, ethyl 3-sulfanylbutanoate 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.

As a certified reference material (CRM), ethyl 3-sulfanylbutanoate 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.
