Description

The occurrence of 6-(2-CHLOROACETYL)-8-FLUORO-2H-BENZO[B][1,4]OXAZIN-3(4H)-ONE 698984-57-5 FD7285 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-(2-CHLOROACETYL)-8-FLUORO-2H-BENZO[B][1,4]OXAZIN-3(4H)-ONE 698984-57-5 FD7285 (CAS 698984-57-5) is a high-purity analytical reference standard with the molecular formula C10H7ClFNO3 and a molecular weight of 243.62 g/mol.

6-(2-CHLOROACETYL)-8-FLUORO-2H-BENZO[B][1,4]OXAZIN-3(4H)-ONE 698984-57-5 FD7285 (C10H7ClFNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
