Chemical Structure
Description
The occurrence of 5-Fluoro-1-(3-oxo-1,3-dihydroisobenzofuran-1-yl)pyrimidine-2,4(1H,3H)-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Fluoro-1-(3-oxo-1,3-dihydroisobenzofuran-1-yl)pyrimidine-2,4(1H,3H)-dione (CAS 81820-68-0), a certified reference material (molecular formula C12H7FN2O4, MW 262.19 g/mol) for analytical method development and quality control.
The molecular framework of 5-Fluoro-1-(3-oxo-1,3-dihydroisobenzofuran-1-yl)pyrimidine-2,4(1H,3H)-dione (C12H7FN2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
