Description

22S,23S-Epibrassinolide is a highly active, naturally occurring brassinosteroid plant growth regulator. This compound is valued for its potent ability to enhance plant stress tolerance, promote cell division and elongation, and improve crop yield and quality. It is an essential tool for agricultural researchers, formulators of high-performance plant biostimulants, and producers in the horticulture and commercial farming sectors seeking to optimize plant health and productivity.

Application

• Plant Growth Regulation: Used to stimulate cell division and elongation, leading to improved stem strength, root development, and overall plant vigor.
• Crop Yield Enhancement: Applied to increase fruit set, seed production, and final crop yield in cereals, vegetables, and fruits.
• Abiotic Stress Mitigation: Helps plants cope with environmental stresses such as drought, salinity, temperature extremes, and heavy metal toxicity.
• Biostimulant Formulation: A key active ingredient in advanced foliar sprays, seed treatments, and soil amendment products for sustainable agriculture.
• Research and Development: Serves as a critical standard and reagent in plant physiology, biochemistry, and agrochemical research.
• Post-Harvest Quality Improvement: Can be used to enhance the shelf life and quality of certain fruits and vegetables.

Quality Control

Our 22S,23S-Epibrassinolide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, to ensure it meets high-purity standards suitable for research and formulation. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (or as specified on the label). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment and away from direct light exposure to maintain stability and potency.
