Chemical Structure

2-O-α-D-Glucopyranosyl-D-galactopyranose CAS 7368-73-2 chemical structure

Description

The molecular framework of 2-O-α-D-Glucopyranosyl-D-galactopyranose (C12H22O11) 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.

2-O-α-D-Glucopyranosyl-D-galactopyranose (CAS 7368-73-2) is a high-purity analytical reference standard with the molecular formula C12H22O11 and a molecular weight of 342.30 g/mol.

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.
