Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Sodium 2,3-dihydroxypropane-1-sulfonate (CAS 35396-47-5) is a high-purity analytical reference standard with the molecular formula C3H7O5SNa and a molecular weight of 178.13 g/mol.
The molecular framework of Sodium 2,3-dihydroxypropane-1-sulfonate (C3H7O5SNa) is characterized by a sulfone group, a carboxylic acid group, an ether linkage. 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.
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.
