Description

Thidiazuron is a highly effective plant growth regulator belonging to the phenylurea class of compounds. Its primary value lies in its potent cytokinin-like activity, which makes it a critical tool for inducing controlled defoliation and promoting lateral bud break in various crops. This product is essential for agricultural professionals and researchers focused on improving crop yield, managing harvest timing, and advancing plant tissue culture techniques. Thidiazuron CAS NO 41118-83-6 is a key ingredient in modern, precision agriculture.

Application

• Cotton Defoliant: Widely used as a harvest aid chemical to induce leaf drop in cotton plants, facilitating mechanical harvesting and improving lint quality.
• Fruit Thinning: Applied in orchards to regulate fruit set and size, promoting the development of larger, higher-quality fruits in apples, pears, and other tree crops.
• Plant Tissue Culture: Serves as a potent cytokinin substitute to stimulate shoot proliferation, callus induction, and somatic embryogenesis in micropropagation protocols.
• Lateral Bud Release: Promotes the growth of lateral buds in vines and ornamental plants, leading to bushier growth and increased flowering.
• Weed Control Research: Used in scientific studies as a model compound to understand plant hormone pathways and develop novel herbicide or plant growth regulator chemistries.
• Turf Management: Employed in specialized formulations to manage growth and improve the density and quality of turfgrass on golf courses and sports fields.

Quality Control

Our Thidiazuron is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity verification, to meet exacting technical or research-grade specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee product integrity and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, open flames, and incompatible materials. Due to its light-sensitive nature, the container should be opaque or stored in a dark place.
