2,4-Dichlorophenoxyacetic acid (Cat No.: R010527) is a widely used systemic herbicide belonging to the phenoxy family of chemicals. It functions as a synthetic auxin, mimicking plant growth hormones and causing uncontrolled, lethal growth in broadleaf weeds while leaving grasses largely unaffected. 2,4-D is commonly applied in agriculture, lawn care, and forestry to manage unwanted vegetation. It is available in various salt and ester forms and is known for its effectiveness, low cost, and broad-spectrum weed control capabilities, though environmental concerns persist.
