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 Sodium 1-hydroxy-2,5-dioxopyrrolidine-3-sulfonate hydrate.
Sodium 1-hydroxy-2,5-dioxopyrrolidine-3-sulfonate hydrate (CAS 304671-62-3), molecular formula C4H4NO6SNaH2O and molecular weight 235.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Sodium 1-hydroxy-2,5-dioxopyrrolidine-3-sulfonate hydrate (C4H4NO6SNaH2O) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
