Description

Diquat Dibromide CAS NO 231-36-7 is a quaternary ammonium salt widely recognized as a potent, non-selective herbicide and desiccant. Its primary value lies in its fast-acting contact activity, which rapidly disrupts plant cell membranes upon application. This compound is essential for agricultural professionals, industrial vegetation managers, and researchers in the agrochemical sector seeking effective weed control and crop desiccation solutions.

Application

• Agricultural Herbicide: Used as a non-selective contact herbicide for the control of a broad spectrum of annual broadleaf and grass weeds in various cropping systems.
• Crop Desiccation: Employed as a pre-harvest desiccant to dry down canopy vegetation in crops like potatoes, sunflowers, and seed crops to facilitate mechanical harvesting.
• Aquatic Weed Management: Applied for the control of floating and submerged aquatic weeds in irrigation canals, ponds, and other non-potable water bodies.
• Industrial Vegetation Control: Utilized for total vegetation management on non-crop areas such as railway embankments, industrial sites, and around storage yards.
• Defoliant: Acts as a defoliant to remove leaves from plants, often used in specific agricultural protocols to prepare plants for harvest.
• Research & Development: Serves as a key reference standard and active ingredient in agrochemical R&D for formulating new herbicidal products and studying plant physiology.

Quality Control

Our Diquat Dibromide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical tests including HPLC for assay, loss on drying, and residue on ignition. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment to guarantee compliance with agreed technical 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. As a strong oxidizer, it should be stored separately from combustible materials, reducing agents, and strong acids.
