Description

Precocene Ii CAS NO 644-06-4 is a synthetic analog of juvenile hormone, specifically known as 6,7-dimethoxy-2,2-dimethylchromene. This compound is valued for its potent and specific biological activity as a juvenile hormone antagonist, disrupting insect development and reproduction. It is a critical research and development tool for entomologists, agrochemical scientists, and manufacturers focused on developing novel insect growth regulators and pest management solutions.

Application

• Agrochemical Research & Development: A key intermediate and active ingredient candidate for developing next-generation insect growth regulators (IGRs) and insecticidal formulations.
• Academic & Entomological Studies: Used extensively in laboratory research to study insect endocrinology, metamorphosis, reproduction, and the mechanisms of juvenile hormone action.
• Pest Control Product Development: Serves as a model compound for creating targeted pest management products that interfere with specific life stages of insects, offering potential for integrated pest management (IPM) strategies.
• Biochemical Reagent: Employed as a precise biochemical tool to induce precocious metamorphosis in insect models, facilitating genetic and physiological studies.
