Chemical Structure
Description
The occurrence of 1-(3-Fluorophenyl)-1,4-dihydropyrazine-2,3-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.
1-(3-Fluorophenyl)-1,4-dihydropyrazine-2,3-dione (CAS 899724-69-7) is a high-purity analytical reference standard with the molecular formula C10H7FN2O2 and a molecular weight of 206.17 g/mol.
The molecular framework of 1-(3-Fluorophenyl)-1,4-dihydropyrazine-2,3-dione (C10H7FN2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(3-Fluorophenyl)-1,4-dihydropyrazine-2,3-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
