Chemical Structure
Description
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
Enalapril Impurity 36 (CAS CATO-C4X-133436) is a certified pharmaceutical impurity reference standard with the molecular formula C20H27N3O6 and a molecular weight of 405.44 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Enalapril Impurity 36 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.44 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.
