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 2,4,6-Trinitrobenzenesulfonic acid（5%(w/v) in H2O）.
2,4,6-Trinitrobenzenesulfonic acid（5%(w/v) in H2O） (CAS 2508-19-2), molecular formula C6H3N3O9S and molecular weight 293.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H3N3O9S, 2,4,6-Trinitrobenzenesulfonic acid（5%(w/v) in H2O） contains a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 293.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
