Compared with other compounds in its class, the molecular weight of 68.08 g/mol gives Avibactam Impurity 49 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Avibactam Impurity 49 (CAS 288-31-3), molecular formula C3H4N2 and molecular weight 68.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Avibactam Impurity 49 (C3H4N2) is characterized by a nitrile group. 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. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Avibactam Impurity 49 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.
