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 5-Bromo-1H-imidazole-4-carbaldehyde.
5-Bromo-1H-imidazole-4-carbaldehyde (CAS 50743-01-6) is a high-purity analytical reference standard with the molecular formula C4H3BrN2O and a molecular weight of 174.98 g/mol.
The molecular framework of 5-Bromo-1H-imidazole-4-carbaldehyde (C4H3BrN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
