The Uses of 2-Chlorophenothiazine
Metabolite of Chloropromazine
General Description
2-Chlorophenothiazine is an methylene blue (MB) derivative. Transient resonance Raman and absorption spectra of the lowest excited triplet states T1 and the cation radicals of 2-chlorophenothiazine have been investigated. Molecular semiconductors based on the 1:1 charge-transfer complexes of 2-chlorophenothiazine with 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) have been investigated by X-ray powder diffraction.
Synthesis
(1)2-(3-chloro-phenyl-) benzaminic acid is in the presence of the iron of catalytic amount, in 160～180℃ of following depickling reaction generation m-chloro pentanoic that take place;by step (1) gained m-chloro pentanoic in the presence of the iodine of catalytic amount, at 110～150℃ ring-closure reactions taking place down with sulphur makes described 2-chloro phenothiazine.
