Chemical Structure

D-Mannuronic Acid Sodium Salt CAS 921-56-2 chemical structure

Description

CATO supplies D-Mannuronic Acid Sodium Salt (CAS 921-56-2), a certified reference material (molecular formula C6H9O7Na, MW 216.12 g/mol) for analytical method development and quality control.

The molecular framework of D-Mannuronic Acid Sodium Salt (C6H9O7Na) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
