Febuxostat impurity 36 CAS 1805770-40-4

Description

Compared with other compounds in its class, the molecular weight of 200.24 g/mol gives Febuxostat impurity 36 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Febuxostat impurity 36 (CAS 1805770-40-4) is a certified pharmaceutical impurity reference standard with the molecular formula C12H12N2O and a molecular weight of 200.24 g/mol.

Based on its molecular formula C12H12N2O, Febuxostat impurity 36 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
