Chemical Structure
Description
The occurrence of Flupyrsulfuron-methyl is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Flupyrsulfuron-methyl (CAS 144740-53-4) is a high-purity analytical reference standard with the molecular formula C15H14F3N5O7S and a molecular weight of 465.36 g/mol.
The molecular framework of Flupyrsulfuron-methyl (C15H14F3N5O7S) is characterized by a flavonoid core, an amide group, a sulfone 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.
