Phenothiazine (CAS 92-84-2) has a notable history and continued relevance in the agrochemical sector, primarily for its effectiveness as an anthelmintic in livestock and as an insecticide for fruit trees. Its chemical properties allow it to target and combat parasitic worms in cattle, horses, and sheep, addressing common health issues that can impact herd productivity. The compound's ability to disrupt the digestive processes of these internal parasites has made it a valuable tool in veterinary medicine for many years.

In the realm of crop protection, Phenothiazine has also been employed as an insecticide, particularly for fruit trees. Its application helps to control pest populations that can damage crops, leading to reduced yields and quality. While newer, more specific pesticides have emerged, the historical significance and certain applications of Phenothiazine in agrochemistry remain noteworthy. The continuous search for effective and safe agricultural inputs means that compounds like Phenothiazine, with their proven track records, continue to be of interest to formulators and researchers.

The sourcing of Phenothiazine for agrochemical applications often requires specific grades and formulations to ensure efficacy and compliance with agricultural regulations. Understanding the history and the current market for Phenothiazine is important for anyone involved in the production or use of agrochemicals. As the agricultural industry evolves, the role of versatile chemicals like Phenothiazine in protecting both livestock and crops remains a subject of ongoing relevance and potential innovation.
