Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Oxopropane-1-sulfonic acid.
2-Oxopropane-1-sulfonic acid (CAS 4721-41-9), molecular formula C3H6O4S and molecular weight 138.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Oxopropane-1-sulfonic acid (C3H6O4S) contains a sulfone group, a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 138.14 g/mol, it falls into the low-molecular-weight range.
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.
