Description

Diuron CAS NO 330-54-1 is a selective, substituted urea herbicide belonging to the phenylurea class. It is valued for its long-lasting residual activity and effectiveness in controlling a broad spectrum of annual and perennial grasses and broadleaf weeds. This compound is a critical active ingredient for non-crop and industrial vegetation management, as well as selective use in certain agricultural settings. Industries requiring reliable, persistent weed control solutions rely on its consistent quality and performance.

Application

• Non-Crop Area Weed Control: Used for total vegetation management on industrial sites, railways, roadsides, and utility rights-of-way.
• Agricultural Use: Selective pre-emergence and early post-emergence herbicide in crops such as cotton, sugarcane, alfalfa, and certain fruit orchards.
• Aquatic Vegetation Management: Applied for controlling unwanted weeds and algae in irrigation canals, drainage ditches, and ponds.
• Forestry: Employed in site preparation and conifer release programs to manage competing vegetation.
• Turf Management: Used on certain turfgrass species for pre-emergent control of crabgrass and other weeds.
• Manufacturing of Formulations: Serves as a key technical-grade active ingredient (TGAI) for producing various herbicide formulations like wettable powders (WP) and suspension concentrates (SC).

Quality Control

Our Diuron is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC for assay and impurity profiling. We provide full traceability and support our products with Certificates of Analysis (COA) to confirm compliance with relevant specifications and regulatory guidelines, including EPA and EU standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 absorption of atmospheric moisture. Keep away from heat, sparks, and open flame.
