Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 517.53 g/mol gives Naltrexone-3-β-D-glucuronide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Naltrexone-3-β-D-glucuronide (CAS 76630-71-2), molecular formula C26H31NO10 and molecular weight 517.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Naltrexone-3-β-D-glucuronide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 517.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
