Chemical Structure

Irbesartan-D9 CAS 1242281-36-2 chemical structure

Description

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.

CATO supplies Irbesartan-D9 (CAS 1242281-36-2), a certified reference material (molecular formula C25H19D9N6O, MW 437.58 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, Irbesartan-D9 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.58 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
