Chemical Structure
Description
The occurrence of 5-Mercapto-1H-tetrazole-1-methanesulfonic Acid Disodium Salt is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Mercapto-1H-tetrazole-1-methanesulfonic Acid Disodium Salt (CAS 66242-82-8), molecular formula C9H11N3S and molecular weight 193.27 g/mol, is a CATO reference standard with documented purity and traceability.
5-Mercapto-1H-tetrazole-1-methanesulfonic Acid Disodium Salt (C9H11N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
