Benzophenone has been found in some fungi, fruits and plants, including grapes. [4] It is a white solid with a low melting point and rose-like odor [5] that is soluble in organic solvents. Benzophenone is the simplest diaromatic ketone.
Lorazepam can be made using 2-amino-2′,5-dichlorobenzophenone (a derivative of 2-amino-5-chlorobenzophenone), which is first reacted with hydroxylamine, the obtained product is then reacted with chloroacetyl chloride to give 6-chloro-2-chlormethyl-4-(2′-chlorophenyl)quinazolin-3-oxide, a reaction with methylamine produces ring expansion and rearrangement, which forms 7-chloro-2-methylamino ...
4,4’-Dichlorobenzophenone is prepared by the acylation of chlorobenzene with 4-chlorobenzoyl chloride. The conversion is typically conducted in the presence of an aluminium chloride catalyst in a petroleum ether solvent. ClC 6 H 5 C(O)Cl + C 6 H 5 Cl → (ClC 6 H 4) 2 CO + HCl
Oxybenzone or benzophenone-3 or BP-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound belonging to the class of aromatic ketones known as benzophenones.
Halogenation of the alcohol in muriatic acid afforded 4-Chlorobenzhydryl chloride [134-83-8] (3). Alkylation with one equivalent of piperazine gives 1-(4-Chlorobenzhydryl)piperazine [303-26-4] ( 4 ). Alkylation of the remaining nitrogen with Cinnamyl Bromide [4392-24-9] ( 5 ) completed the synthesis of Clocinizine ( 6 ).
4-Chlorobenzoic acid is an organic compound with the molecular formula ClC 6 H 4 CO 2 H. It is a white solid that is soluble in some organic solvents and in aqueous base. 4-Chlorobenzoic acid is prepared by oxidation of 4-chlorotoluene .
Sulisobenzone (benzophenone-4) is an ingredient in some sunscreens which protects the skin from damage by UVB and UVA ultraviolet light. [ 2 ] [ 3 ] Its sodium salt, sulisobenzone sodium , is also referred to as benzophenone-5 .
Clorazepate is used in the treatment of anxiety disorders and insomnia. It may also be prescribed as an anticonvulsant or muscle relaxant. [4] It is also used as a premedication. [5] Clorazepate is prescribed principally in the treatment of alcohol withdrawal and epilepsy, although it is also a useful anxiolytic because of its long half-life ...
