4-Chlorophenoxyacetic acid (4-CPA) is a synthetic auxin that is widely used as a plant growth regulator, herbicide, and hormone in agriculture. It is a white crystalline powder that is soluble in water and commonly used to control the growth of broadleaf weeds in crops like wheat, maize, and rice. 4-CPA works by mimicking the natural plant hormone indoleacetic acid (IAA) and stimulating plant growth or inhibiting it depending on the concentration used. It is also used in tissue culture to induce root formation and is being studied for its potential use in cancer therapy.
