Brimonidine Impurity 20 CAS 1217439-05-8

Description

Compared with other compounds in its class, the molecular weight of 283.15 g/mol gives Brimonidine Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Brimonidine Impurity 20 (CAS 1217439-05-8) is a certified pharmaceutical impurity reference standard with the molecular formula C9H7BrN4S and a molecular weight of 283.15 g/mol.

Structurally, Brimonidine Impurity 20 (C9H7BrN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 283.15 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
