Chemical Structure

(2R,3R,4S,5R)-2,3,4,5,6-pentahydroxyhexanoic acid CAS 20246-53-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(2R,3R,4S,5R)-2,3,4,5,6-pentahydroxyhexanoic acid (CAS 20246-53-1), molecular formula C6H12O7 and molecular weight 196.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2R,3R,4S,5R)-2,3,4,5,6-pentahydroxyhexanoic acid (C6H12O7) 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.

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.
