Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-1-ethyl-1H-imidazole hydrochloride.
2-Bromo-1-ethyl-1H-imidazole hydrochloride (CAS 1390654-34-8) is a high-purity analytical reference standard with the molecular formula C5H7BrN2HCl and a molecular weight of 211.49 g/mol.
2-Bromo-1-ethyl-1H-imidazole hydrochloride (C5H7BrN2HCl) contains a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
