Chemical Structure

3-(Ethylsulfonyl)propanoic acid CAS 89211-36-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Ethylsulfonyl)propanoic acid.

3-(Ethylsulfonyl)propanoic acid (CAS 89211-36-9), molecular formula C5H10O4S and molecular weight 166.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(Ethylsulfonyl)propanoic acid (C5H10O4S) is characterized by a carbohydrate-derived structure, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
