Description

Ethephon CAS NO 16672-87-0 is a highly effective plant growth regulator belonging to the organophosphonate class. It functions as a source of ethylene, a key plant hormone, to precisely control and accelerate critical physiological processes in a wide range of crops. This compound is essential for agricultural professionals and agrochemical formulators seeking to enhance crop uniformity, manage harvest timing, and improve overall yield. Its reliable performance makes it a cornerstone technology in modern, high-efficiency farming systems worldwide.

Application

• Fruit Ripening & Abscission Agent: Promotes uniform ripening and facilitates mechanical harvesting of crops such as pineapples, tomatoes, cherries, and coffee.
• Flowering & Sex Expression Modifier: Used to induce flowering in pineapples and promote female flower production in cucurbits like cucumbers and melons.
• Growth Inhibition & Lodging Control: Applied to cereal crops like wheat and barley to shorten stems, reduce lodging (falling over), and improve standability.
• Latex Flow Stimulant: Enhances the yield of natural rubber latex from rubber trees (*Hevea brasiliensis*).
• Tobacco Sucker Control: Suppresses the growth of axillary buds (suckers) in tobacco, directing energy to the main leaves.
• Cotton Defoliation: Aids in the removal of leaves from cotton plants prior to harvest, improving picking efficiency and fiber quality.
• Industrial Research & Formulation: Serves as a key active ingredient for R&D and the production of commercial-grade plant growth regulator formulations.

Quality Control

Our Ethephon is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC assay and impurity profiling, to meet exacting technical and agricultural grade specifications. A detailed Certificate of Analysis (COA) documenting identity, purity, and relevant physical parameters is provided with every shipment to guarantee product integrity for your formulations and applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids, bases, and oxidizing agents. Due to its acidic nature, containers should be made of corrosion-resistant materials. Keep the container tightly sealed when not in use to maintain stability.
