Chemical Structure
Description
Irbesartan N-beta-D-Glucuronide (CAS 160205-58-3), molecular formula C31H36N6O7 and molecular weight 604.65 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, Irbesartan N-beta-D-Glucuronide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 604.65 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.
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.
