Brimonidine Impurity 24 CAS CATO-C4X-156624

Description

Compared with other compounds in its class, the molecular weight of 247.68 g/mol gives Brimonidine Impurity 24 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Brimonidine Impurity 24 (CAS CATO-C4X-156624), a pharmacopoeial impurity reference standard (molecular formula C11H10ClN5, MW 247.68 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C11H10ClN5, Brimonidine Impurity 24 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.68 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
