(2-Chloroethyl) phosphonic acid (Cat No.: R017425), commonly known as ethephon, is a plant growth regulator widely used in agriculture and horticulture. It releases ethylene gas upon decomposition, which influences various physiological processes in plants, including fruit ripening, flower induction, leaf abscission, and senescence. Ethephon is applied to crops such as cotton, pineapple, and tomatoes to enhance harvest timing and yield. Its water solubility and ability to penetrate plant tissues make it an effective and widely adopted tool in plant growth management.
