Overview
Brassinolide is a naturally occurring plant steroid classified as a brassinosteroid. It plays a crucial role in plant growth and development, particularly in cell elongation, division, and stress resistance. Discovered in the 1970s, it has since become a valuable tool in modern agriculture for improving crop yields and quality. Unlike synthetic plant hormones, brassinolide is derived from natural sources and is considered environmentally friendly. Its ability to enhance plant resilience against abiotic stresses like drought and salinity makes it a popular choice among farmers and agricultural researchers.
Physical and Chemical Properties
Brassinolide is a white to off-white crystalline powder with a molecular weight of 480.68 g/mol. It is soluble in organic solvents such as ethanol and methanol but has limited solubility in water. The compound is stable under normal storage conditions but should be protected from light and moisture to maintain efficacy. Its melting point ranges between 256-258°C, and it exhibits low volatility. The molecular structure includes a steroidal backbone with hydroxyl groups, which are critical for its biological activity. These properties make it suitable for formulation into various agricultural products, including foliar sprays and seed treatments.
Main Applications
Brassinolide is primarily used in agriculture to promote plant growth and improve stress tolerance. It is applied to crops such as rice, wheat, and vegetables to enhance yield and quality. The compound works by stimulating cell elongation and division, leading to stronger stems and larger leaves. In addition to growth promotion, brassinolide helps plants withstand environmental stresses like drought, salinity, and extreme temperatures. It is also used in horticulture to improve flower quality and fruit setting. Its versatility and low toxicity make it a preferred choice for sustainable farming practices.
Safety and Storage
Brassinolide is considered low in toxicity to humans and animals, but proper handling is still recommended. Use gloves and avoid inhalation or direct contact with skin and eyes. In case of exposure, rinse thoroughly with water and seek medical advice if irritation persists. Store brassinolide in a cool, dry place away from light and moisture to prevent degradation. Keep containers tightly sealed and out of reach of children and pets. Proper storage ensures the compound remains effective for its intended agricultural applications.
B2B Procurement Guide
When procuring brassinolide for B2B purposes, prioritize suppliers with certifications such as ISO or GMP to ensure product quality. Verify the purity level, preferably ≥90%, and request third-party lab test reports if available. Bulk purchases often come with discounts, so negotiate pricing based on volume. Consider the formulation type (e.g., powder or liquid) based on your application needs. Check for compatibility with other agrochemicals if used in combination. Reliable suppliers should provide technical support and documentation, including safety data sheets (SDS) and application guidelines.
