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 (S)-2-((Methylsulfonyl)oxy)propanoic acid.
(S)-2-((Methylsulfonyl)oxy)propanoic acid (CAS 66423-08-3), molecular formula C4H8O5S and molecular weight 168.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H8O5S, (S)-2-((Methylsulfonyl)oxy)propanoic acid contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 168.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
