Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 327.33 g/mol gives Baloxavir Impurity 1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Baloxavir Impurity 1 (CAS 1985607-70-2), a pharmacopoeial impurity reference standard (molecular formula C17H17N3O4, MW 327.33 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Baloxavir Impurity 1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
