Chemical Structure

Sodium 5-sulphosalicylate CAS 831-54-9 chemical structure

Description

The occurrence of Sodium 5-sulphosalicylate is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sodium 5-sulphosalicylate (CAS 831-54-9) is a high-purity analytical reference standard with the molecular formula C7H5O6SNa and a molecular weight of 240.16 g/mol.

Sodium 5-sulphosalicylate (C7H5O6SNa) 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
