Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 222.17 g/mol gives 2,2,6,6-Tetramethylpiperidinehydrobromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,2,6,6-Tetramethylpiperidinehydrobromide (CAS 935-21-7) is a high-purity analytical reference standard with the molecular formula C9H19NHBr and a molecular weight of 222.17 g/mol.
The molecular framework of 2,2,6,6-Tetramethylpiperidinehydrobromide (C9H19NHBr) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
