Chemical Structure
Description
6-[2-(2-chloro-4-pyridyl)ethynyl]-1H-pyrido[2,3-d]pyrimidin-4-one (CAS 2585151-47-7) is a high-purity analytical reference standard with the molecular formula C14H7ClN4O and a molecular weight of 282.68 g/mol.
The molecular framework of 6-[2-(2-chloro-4-pyridyl)ethynyl]-1H-pyrido[2,3-d]pyrimidin-4-one (C14H7ClN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
