The mysteries of plant cell growth may be unlocked through a surprisingly simple chemical compound. 4-Chlorophenoxyacetic acid (4-CPA) , a product now available through Fisher Scientific in 25-gram quantities, has demonstrated significant effects on plant cell expansion, root initiation, and adventitious shoot formation.
Also known as para-chlorophenoxyacetic acid , 4-CPA appears as an off-white to brownish crystalline powder with a melting point between 157–159°C. The compound dissolves readily in ethanol and potassium hydroxide solutions. However, researchers caution that it may be harmful if ingested, requiring proper safety precautions during handling.
As a plant growth regulator, 4-CPA holds considerable promise for agricultural and horticultural applications. The compound has shown efficacy in promoting fruit enlargement, potentially increasing crop yields. Its ability to accelerate propagation processes also makes it valuable for plant tissue culture techniques.
Beyond practical applications, 4-CPA serves as an important tool for plant physiology research. Scientists are utilizing the compound to investigate the regulatory mechanisms behind plant growth and development, potentially leading to breakthroughs in cultivation methods and crop improvement strategies.
