Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 172.02 g/mol gives Phloroglucinol Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Phloroglucinol Impurity 22 (CAS 106-40-1) is a certified pharmaceutical impurity reference standard with the molecular formula C6H6BrN and a molecular weight of 172.02 g/mol.
Phloroglucinol Impurity 22 (C6H6BrN) contains a nitrile group, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
