Baloxavir Impurity 52 CAS 1228258-40-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Baloxavir Impurity 52.

CATO supplies Baloxavir Impurity 52 (CAS 1228258-40-9), a pharmacopoeial impurity reference standard (molecular formula C6H15NO3, MW 149.19 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Baloxavir Impurity 52 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.19 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 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.
