Triclopyr 2-butoxyethyl ester

Triclopyr 2-butoxyethyl ester (CAS 64700-56-7, EC 265-024-8, formula C13H16Cl3NO4) is a selective systemic herbicide active ingredient, commercially known under trade names including Garlon 4 and Turflon, and referenced in industry as M 4021 or m4021. It belongs to the pyridine carboxylic acid herbicide class.

The compound controls broadleaf weeds and woody vegetation by mimicking natural plant growth hormones, causing uncontrolled cell division that leads to plant death. It is used in agricultural crop protection programs, forestry site management, and rights-of-way maintenance where selective elimination of hardwood species and brush is required without affecting established grasses.

Triclopyr 2-butoxyethyl ester is supplied as a technical-grade active ingredient and is subject to REACH registration requirements within the European Union. Procurement quantities are available in bulk and intermediate packaging formats. Buyers should confirm current regulatory status and import documentation requirements prior to ordering.
