Description

Demeton CAS NO 8065-48-3 is a systemic organophosphate insecticide and acaricide, historically significant as one of the first compounds of its class. Its core value lies in its dual action as both a contact and systemic poison, effectively controlling a wide range of sucking and chewing pests. This product is primarily needed by agricultural chemical formulators and researchers in the agrochemical industry for crop protection applications, as well as by professionals involved in pest management research and the development of pesticide resistance studies.

Application

• Agricultural Insecticide: Used in the control of aphids, mites, thrips, and other sucking insects on a variety of field crops, fruits, and vegetables.
• Systemic Pest Control: Applied to soil or foliage, it is absorbed and translocated within the plant, providing protection from internal feeders.
• Acaricide Formulations: A key active ingredient in mixtures targeting spider mites and other phytophagous mites.
• Pesticide Intermediate: Serves as a starting material or precursor in the synthesis of other organophosphate compounds.
• Research & Development: Used in biochemical and toxicological studies related to cholinesterase inhibition and pesticide mode of action.
• Historical Reference Standard: Employed in environmental testing and regulatory analysis as a reference compound for residue detection.

Quality Control

Our Demeton is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. While typically supplied as a technical grade material, specifications for purity and impurity profiles are rigorously controlled. A Certificate of Analysis (COA) detailing key parameters such as assay, identity, and relevant impurities is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its properties as a strong acid/organic solvent mixture and high volatility, containers must be kept tightly sealed and upright to prevent leakage and vapor release. Recommended storage temperature is 2-8°C for extended stability. Keep away from incompatible materials such as strong oxidizers and bases.
