Chemical Structure

3-Methanesulfonylcyclopentan-1-one CAS 1491178-97-2 chemical structure

Description

Based on its molecular formula C6H10O3S, 3-Methanesulfonylcyclopentan-1-one contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 162.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

CATO supplies 3-Methanesulfonylcyclopentan-1-one (CAS 1491178-97-2), a certified reference material (molecular formula C6H10O3S, MW 162.21 g/mol) for analytical method development and quality control.

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.
