The occurrence of Sulfoacetic acid is closely related to a sulfone group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Sulfoacetic acid (CAS 123-43-3) is a high-purity analytical reference standard with the molecular formula C2H4O5S and a molecular weight of 140.12 g/mol.
Sulfoacetic acid (C2H4O5S) contains a sulfone group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
