Avibactam Impurity 64 CAS CATO-C4X-134864

Description

Compared with other compounds in its class, the molecular weight of 159.19 g/mol gives Avibactam Impurity 64 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Avibactam Impurity 64 (CAS CATO-C4X-134864), a pharmacopoeial impurity reference standard (molecular formula C6H13N3O2, MW 159.19 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Avibactam Impurity 64 (C6H13N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), Avibactam Impurity 64 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.
