Phenothiazine Uses
Phenothiazine serves as a polymerization inhibitor for vinyl acetate. It is also a raw material for anti-aging agents in rubber, synthetic dyes, and various drugs. Additionally, it functions as an insecticide for fruit trees and as an insect repellent for livestock.
Furthermore, phenothiazines effectively treat acute and chronic schizophrenia, mania, and reactive psychosis. They help manage symptoms like excitement, aggression, hallucinations, and delusions.
Moreover, phenothiazine acts as an intermediate in producing methylene blue dyes. It is crucial for manufacturing depressants and antihistamines, including chlorpromazine, perphenazine, promethazine, and thioridazine.
Finally, phenothiazine is vital for making medicines and dyes. It also supports synthetic products and serves as an insecticide. Notably, it affects various parasites in livestock, including twirling belly worms and ovine nematodes.
