Chemical Structure

Ethyl 3-(methylsulfonyl)propanoate CAS 118675-14-2 chemical structure

Description

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.

Ethyl 3-(methylsulfonyl)propanoate (CAS 118675-14-2) is a high-purity analytical reference standard with the molecular formula C6H12O4S and a molecular weight of 180.22 g/mol.

Structurally, Ethyl 3-(methylsulfonyl)propanoate (C6H12O4S) 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 180.22 g/mol, it falls into the medium-molecular-weight range.

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.
