Baloxavir Impurity 51 CAS 2136287-61-9

Description

The occurrence of Baloxavir Impurity 51 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Baloxavir Impurity 51 (CAS 2136287-61-9, C24H33N3O8) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Baloxavir Impurity 51 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 491.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
