Chemical Structure
Description
The molecular framework of 4-(1-Bromoethyl)pyridine hydrobromide (C7H8BrNHBr) 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.
4-(1-Bromoethyl)pyridine hydrobromide (CAS 89694-53-1) is a high-purity analytical reference standard with the molecular formula C7H8BrNHBr and a molecular weight of 266.96 g/mol.
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), 4-(1-Bromoethyl)pyridine 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.
