Chemical Structure

4-(Ethylsulfonyl)butanoic acid CAS 99116-13-9 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.

4-(Ethylsulfonyl)butanoic acid (CAS 99116-13-9) is a high-purity analytical reference standard with the molecular formula C6H12O4S and a molecular weight of 180.22 g/mol.

Based on its molecular formula C6H12O4S, 4-(Ethylsulfonyl)butanoic acid 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 180.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
