Chemical Structure
Description
The occurrence of Diethyl (5-bromopyridin-2-yl)phosphonate is closely related to an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diethyl (5-bromopyridin-2-yl)phosphonate (CAS 344891-78-7) is a high-purity analytical reference standard with the molecular formula C9H13BrNO3P and a molecular weight of 294.08 g/mol.
The molecular framework of Diethyl (5-bromopyridin-2-yl)phosphonate (C9H13BrNO3P) is characterized by an amide group, a phosphonate group, a carboxylic acid 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.
