2,4,6-trihydroxybenzenesulfonic acid CAS 91147-79-4 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-trihydroxybenzenesulfonic acid.

2,4,6-trihydroxybenzenesulfonic acid (CAS 91147-79-4), molecular formula C6H6O6S and molecular weight 206.17 g/mol, is a CATO reference standard with documented purity and traceability.

2,4,6-trihydroxybenzenesulfonic acid (C6H6O6S) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
