Methyl 3-(Chlorosulfonyl)propanoate CAS 15441-07-3

Description

The occurrence of Methyl 3-(Chlorosulfonyl)propanoate is closely related to a carbohydrate-derived structure, a sulfone group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Methyl 3-(Chlorosulfonyl)propanoate (CAS 15441-07-3), a certified reference material (molecular formula C4H7ClO4S, MW 186.61 g/mol) for analytical method development and quality control.

Structurally, Methyl 3-(Chlorosulfonyl)propanoate (C4H7ClO4S) contains a carbohydrate-derived structure, a sulfone group, chlorine substitution. 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 186.61 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
