Description

Speract CAS NO 76901-59-2 is a synthetic plant growth regulator belonging to the class of brassinosteroids, which are potent phytohormones. This compound is valued for its ability to enhance plant growth, stress tolerance, and crop yield by mimicking natural brassinolide activity. It is primarily utilized by agricultural researchers, agrochemical formulators, and advanced horticultural operations seeking to improve plant vigor and productivity.

Application

• Agricultural Research & Development: Used as a key reference standard and active ingredient in studies on plant physiology, hormone signaling, and stress response mechanisms.
• Agrochemical Formulations: Incorporated into foliar sprays, seed treatments, and biostimulant products designed to promote cell elongation, division, and overall plant growth.
• Crop Yield Enhancement: Applied to improve fruit set, increase seed yield, and enhance the quality of crops such as vegetables, fruits, and cereals under normal or suboptimal growing conditions.
• Stress Mitigation: Employed to bolster plant resilience against abiotic stresses including drought, salinity, and temperature extremes.
• Horticulture and Floriculture: Used to improve the growth, branching, and visual quality of ornamental plants and flowers.

Quality Control

Our Speract is produced and tested under stringent quality management systems. Each batch is analyzed to ensure high purity and consistency, with specifications typically meeting or exceeding research-grade standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
