Chemical Structure
Description
The occurrence of 3-Hydroxy-4-(sulfooxy)benzoic acid is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Hydroxy-4-(sulfooxy)benzoic acid (CAS 76496-12-3), molecular formula C7H6O7S and molecular weight 234.18 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H6O7S, 3-Hydroxy-4-(sulfooxy)benzoic acid contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.18 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.
