Description

Florasulam is a selective, systemic herbicide belonging to the triazolopyrimidine sulfonamide chemical class. It provides highly effective post-emergence control of broadleaf weeds in cereal crops, offering a vital tool for modern agricultural productivity. This compound is essential for formulators and agricultural chemical producers serving the global crop protection industry, where reliable and potent active ingredients are paramount for integrated weed management strategies.

Application

Florasulam is a key active ingredient in modern herbicide formulations, primarily used for broadleaf weed control. Its major applications include:

• Cereal Crop Protection: Post-emergence control of broadleaf weeds in wheat, barley, and other cereal grains.
• Selective Herbicide Formulations: A core component in commercial herbicide products targeting weeds like mayweed, chickweed, and cleavers.
• Tank Mix Solutions: Often combined with other herbicides, such as 2,4-D or MCPA, to broaden the spectrum of weed control and manage resistance.
• Agricultural Research & Development: Used as a reference standard and active ingredient in the development of new crop protection solutions.

Quality Control

Our Florasulam is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to meet technical-grade specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with each shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials.
