Chemical Structure

6-Phosphoglucono-Δ-lactone CAS 2641-81-8 chemical structure

Description

6-Phosphoglucono-Δ-lactone (CAS 2641-81-8), molecular formula C6H11O9P and molecular weight 258.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Phosphoglucono-Δ-lactone (C6H11O9P) is characterized by a carbohydrate-derived structure, a phosphate ester group. 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.
