Midazolam N-β-D-Glucuronide (~90%, contains ~10% inorganic salts) CAS 1033824-50-8

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Midazolam N-β-D-Glucuronide (~90%, contains ~10% inorganic salts) (CAS 1033824-50-8), molecular formula C24H21ClFN3O6 and molecular weight 501.89 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Midazolam N-β-D-Glucuronide (~90%, contains ~10% inorganic salts) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 501.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
