Description

Azinphos-Ethyl is an organophosphate insecticide and acaricide of significant historical importance in agricultural pest management. Its primary value lies in its broad-spectrum activity against a range of chewing and sucking insects, offering effective crop protection. This compound is particularly relevant for professionals in the agrochemical industry involved in research, formulation development, and the study of pest control agents. While its commercial use is now highly restricted in many regions, it remains a critical compound for analytical reference and specialized applications.

Application

• Agrochemical Reference Standard: Serves as a high-purity analytical standard for environmental monitoring, residue analysis, and regulatory compliance testing.
• Research & Development: Used in chemical and toxicological research to study the mode of action, metabolism, and environmental fate of organophosphate compounds.
• Pest Control Formulations: Historically a key active ingredient in insecticidal and acaricidal formulations for protecting fruit, vegetable, and field crops.
• Technical Material: Supplied as a technical-grade material for the manufacture of end-use pesticide products in regions where approved.

Quality Control

Every batch of Azinphos-Ethyl is produced and tested under a stringent quality management system to ensure identity, purity, and consistency. We provide comprehensive analytical documentation, including a detailed Certificate of Analysis (COA) with results from techniques such as HPLC, GC, and NMR. Our quality commitment ensures the material is suitable for its intended use in research and as an analytical standard, meeting the specifications agreed upon with our clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its chemical nature, keep away from strong bases and organic solvents. Ensure the container is kept upright to prevent leakage and store separately from food and feedstuffs.
