Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 241.91 g/mol gives 2-(Bromomethyl)imidazole Hydrobromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(Bromomethyl)imidazole Hydrobromide (CAS 2939-05-1), molecular formula C4H5BrN2HBr and molecular weight 241.91 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Bromomethyl)imidazole Hydrobromide (C4H5BrN2HBr) is characterized by a nitrile group, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(Bromomethyl)imidazole Hydrobromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
