Famotidine impurity 58 CAS CATO-C4X-139258

Description

Compared with other compounds in its class, the molecular weight of 212.26 g/mol gives Famotidine impurity 58 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Famotidine impurity 58 (CAS CATO-C4X-139258) is a certified pharmaceutical impurity reference standard with the molecular formula C5H8N4S2HNa and a molecular weight of 212.26 g/mol.

Based on its molecular formula C5H8N4S2HNa, Famotidine impurity 58 contains a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Famotidine impurity 58 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.
