Description

(+)-Disparlure CAS NO 54910-51-9 is the (+) enantiomer of the gypsy moth (*Lymantria dispar*) sex pheromone, a highly specific and potent semiochemical. This compound is critical for developing environmentally responsible, species-targeted pest management strategies in agriculture and forestry. It is essential for manufacturers of pheromone-based lures, traps, and mating disruption products, as well as for research institutions conducting entomological and ecological studies.

Application

• Integrated Pest Management (IPM): Core component in mating disruption dispensers and attract-and-kill systems for gypsy moth control.
• Monitoring and Trapping: Formulated into lures for population monitoring traps to detect, track, and quantify gypsy moth infestations.
• Agricultural Protection: Used to protect orchards, vineyards, and forests from defoliation by disrupting the mating cycle of the invasive gypsy moth.
• Research and Development: Standard for behavioral studies, electrophysiological research (EAG), and the development of new pheromone-based control technologies.
• Public Health and Quarantine: Deployment in surveillance programs at ports and borders to prevent the spread of this regulated pest.
• Formulation Base: Serves as the active ingredient in the production of commercial pheromone blends, slow-release polymers, and sprayable formulations.

Quality Control

Our (+)-Disparlure is produced and tested to meet the exacting standards required for semiochemical applications. We employ advanced chiral analytical techniques, including GC and HPLC, to ensure high enantiomeric purity and chemical identity. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, isomer content, and stability data, providing traceability and reliable performance for your formulations and research.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at 2-8°C under an inert atmosphere such as argon or nitrogen. Allow the container to reach room temperature before opening to minimize moisture condensation.
