Chemical Structure

D-(+)-Galactose CAS 59-23-4 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.

D-(+)-Galactose (CAS 59-23-4), molecular formula C6H12O6 and molecular weight 180.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, D-(+)-Galactose is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
