Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 154.18 g/mol gives (S)-2-hydroxypropyl methanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-2-hydroxypropyl methanesulfonate (CAS 262423-83-6) is a high-purity analytical reference standard with the molecular formula C4H10O4S and a molecular weight of 154.18 g/mol.
The molecular framework of (S)-2-hydroxypropyl methanesulfonate (C4H10O4S) 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.
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.
