Chemical Structure

Pentosan Polysulfonate CAS 37300-21-3 chemical structure

Description

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

CATO supplies Pentosan Polysulfonate (CAS 37300-21-3), a certified reference material (molecular formula C10H18O21S4, MW 602.50 g/mol) for analytical method development and quality control.

Pentosan Polysulfonate (C10H18O21S4) 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.

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.
