Description

Permethric Acid CAS NO 55701-05-8 is a synthetic pyrethroid acid, a key intermediate in the production of advanced insecticidal compounds. Its primary value lies in its role as a crucial building block for synthesizing potent pyrethroid insecticides, which are valued for their high efficacy and low mammalian toxicity. This chemical is essential for manufacturers in the agrochemical and pharmaceutical industries, where it is used to develop products for crop protection, public health vector control, and veterinary applications.

Application

• Agrochemical Synthesis: Primary intermediate for the manufacture of synthetic pyrethroid insecticides such as permethrin, cypermethrin, and deltamethrin.
• Public Health Products: Used in formulating insecticides for mosquito control programs and household pest management solutions.
• Veterinary Pharmaceuticals: Serves as a precursor in the production of ectoparasiticides for livestock and companion animals.
• Material Protection: Incorporated into treatments for textiles and wood to provide long-lasting protection against insect damage.
• Research & Development: A vital reference standard and starting material for developing novel insecticidal agents in R&D laboratories.
