Chemical Structure

Azlocillin Impurity 5 CAS CATO-C4X-23205 chemical structure

Description

The occurrence of Azlocillin Impurity 5 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Azlocillin Impurity 5 (CAS CATO-C4X-23205), a pharmacopoeial impurity reference standard (molecular formula C22H27N5O8S, MW 521.54 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C22H27N5O8S, Azlocillin Impurity 5 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 521.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Azlocillin Impurity 5 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
