Description

2,4-Dichlorophenoxyacetic Acid Sodium is the sodium salt form of the widely used synthetic auxin, 2,4-D. This compound is valued for its enhanced water solubility and stability compared to the free acid, facilitating its formulation and application. It is a critical active ingredient primarily required by the agrochemical industry for the production of selective, systemic herbicides targeting broadleaf weeds in cereal crops, turf, and non-crop areas.

Application

• Selective Herbicide Formulations: Primary active ingredient in post-emergence herbicides for controlling broadleaf weeds in wheat, corn, rice, and other cereal crops.
• Turf Management: Used in commercial and residential lawn care products to eliminate dandelions, clover, and other common weeds.
• Non-Crop Area Weed Control: Applied in industrial sites, railways, and rights-of-way for vegetation management.
• Research & Development: Serves as a standard and reference material in agricultural research, environmental studies, and analytical laboratories.
• Intermediate for Ester Synthesis: Used as a precursor in the chemical synthesis of various 2,4-D ester derivatives.
