flungeA method of attack with a sword (sabre), propelled from the front foot, like a flèche, but also landing on the front foot, like a lunge.
flunisolideA corticosteroid often used to treat allergic rhinitis.
flunitrazepamA short-acting benzodiazepine derivative with relatively long-lasting sedative effects, used as a hypnotic and as a premedication for anesthesia; 5-(2-fluorophenyl)-1,3-dihydro-1-methyl-7-nitro-2H-1,4-benzodiazepin-2-one, C₁₆H₁₂FN₃O₃.
flunixinA nonsteroidal anti-inflammatory drug, analgesic, and antipyretic used in horses.
fluorantheneA polycyclic aromatic hydrocarbon consisting of a benzene ring attached to each of the rings of a naphthalene molecule; it is carcinogenic, and is a product of incomplete combustion
fluorapatiteA calcium halophosphate mineral, in which fluoride replaces the hydroxide of apatite, that is mined as a phosphate ore, and occurs in the enamel of teeth.
fluorapophylliteA particular apophyllite mineral with more fluorine than hydroxide compared to similar minerals.
fluorateThe oxyanion of fluorine FO₃⁻; any salt containing this ion.
fluoratedCombined with fluorine; subjected to the action of fluoride.
fluorcaphiteA hexagonal-pyramidal mineral containing calcium, cerium, fluorine, oxygen, phosphorus, sodium, and strontium.
fluorellestaditeA rare nesosilicate of calcium, with sulfate and fluorine, belonging to the apatite group.
fluorenamineAny amine containing fluorine and one or more NH₂ groups derived from fluorine-1-carboxylic acid or fluorine-2-carboxylic acid.
fluoreneA polycyclic aromatic hydrocarbon consisting of two benzene rings joined together directly, and also via a methylene bridge; it is used in light-emitting diodes.
fluorenoneAn aromatic compound with the chemical formula C₁₃H₈O, produced from fluorene via oxidation and used in the manufacture of antimalaria drugs.
fluorenylA radical or cation derived from fluorene
fluorenylideneThe divalent radical derived from the bridging methylene group of fluorene
fluorescamineA spiro compound that reacts with primary amines to form highly fluorescent products.
fluoresceTo emit electromagnetic radiation, especially visible light, when absorbing radiation of some other wavelength.
fluoresceinAny of a class of yellow xanthene dyes which are visible when highly diluted; used forensically to detect traces of blood, and in analytical chemistry as an indicator in silver nitrate titrations
fluorescenceThe emission of light (or other electromagnetic radiation) by a material when stimulated by the absorption of radiation or of a subatomic particle.
fluorescinA colourless amorphous substance produced by the reduction of fluorescein, and from which the latter may be formed by oxidation.
fluorescylA univalent radical derived from fluorescein
fluorestradiolAny of several fluoro derivatives of estradiol that have biological activity. Such compounds having isotopically-labelled fluorine atoms are used in medical imaging.
fluorhydroxyapatiteThe tooth mineral formed by the action of fluoride on hydroxyapatite
fluorinatedTreated or reacted with fluorine or hydrofluoric acid.
fluorinationThe introduction of fluorine into a compound by means of a chemical reaction.
fluorinatorSomething that causes fluorine to be added
fluorineThe chemical element (symbol F) with an atomic number of 9. It is the lightest of the halogens, a pale yellow-green, highly reactive gas that attacks all metals.
fluorinelikeResembling or characteristic of fluorine.
fluoriteA widely occurring mineral comprising calcium fluoride plus or minus impurities, of various colours, used as a flux in steelmaking, and in the manufacture of glass, enamels and hydrofluoric acid.
