Chemical Structure

Baloxavir Marboxil Impurity 220 CAS 4883-87-8 chemical structure

Description

CATO manufactures Baloxavir Marboxil Impurity 220 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Baloxavir Marboxil Impurity 220 (CAS 4883-87-8) is a certified pharmaceutical impurity reference standard with the molecular formula C15H24O3S and a molecular weight of 284.41 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Baloxavir Marboxil Impurity 220 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.41 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.
