Description

Delta2-Avermectin B1A is a high-purity, semi-synthetic derivative of the naturally occurring macrocyclic lactone, avermectin B1a. This compound is valued for its potent anthelmintic and insecticidal activity, serving as a critical intermediate in the synthesis of next-generation parasiticides. It is primarily utilized by manufacturers in the animal health, crop protection, and pharmaceutical industries for developing advanced formulations against a broad spectrum of parasites and pests.

Application

• Active Pharmaceutical Ingredient (API) Intermediate: Key precursor in the synthesis of modern veterinary anthelmintic drugs.
• Agrochemical Formulations: Used in the development of high-efficacy insecticides and miticides for crop protection.
• Animal Health Products: Essential for manufacturing end-use products targeting internal and external parasites in livestock and companion animals.
• Research & Development: Serves as a reference standard and starting material for novel parasiticide discovery in life science research.
• Technical Grade Concentrates: Used in the production of technical materials for formulating end-user agricultural solutions.
