Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including D-galactose-5-.
D-galactose-5- (CAS 478518-60-4), molecular formula C5[13C]H12O6 and molecular weight 181.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, D-galactose-5- is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 181.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
