Cas no 82373-95-3 ((22R,23R)-28-Homo Brassinolide)

(22R,23R)-28-Homo Brassinolide is a bioactive brassinosteroid analog known for its potent plant growth-regulating properties. Structurally similar to natural brassinolides, it enhances cell division, elongation, and stress tolerance in plants at low concentrations. Its (22R,23R) stereochemistry ensures high biological activity, improving crop yield and quality under adverse conditions such as drought, salinity, or temperature extremes. The compound is widely studied for its role in modulating photosynthetic efficiency and nutrient uptake. Due to its stability and efficacy, it is utilized in agricultural research and precision farming applications. Its mode of action involves binding to brassinosteroid receptors, triggering downstream signaling pathways that promote plant resilience and productivity.
