Description

(22R,23R)-2A,3A,22,23-Tetrahydroxy-24-Ethyl-β-Homo-7-Oxa-5A-Cholestan-6-One is a high-purity, stereochemically defined brassinosteroid analog, a key class of plant growth regulators. This compound is valued for its potent biological activity in modulating plant physiology, including cell elongation, division, and stress resistance. It is essential for advanced agricultural research, plant biotechnology, and the development of next-generation biostimulants and agrochemicals.

Application

• Plant Physiology & Agricultural Research: A critical reference standard and active ingredient for studying brassinosteroid signaling pathways, hormone interactions, and their effects on crop yield and quality.
• Biostimulant Formulation: Used in the development of high-efficacy plant growth regulators and biostimulant products designed to enhance stress tolerance (drought, salinity, temperature) and improve harvest outcomes.
• Seed Treatment Solutions: Incorporated into seed coating formulations to promote uniform germination, vigorous seedling establishment, and early root development.
• Plant Cell Culture & Tissue Engineering: Employed in in vitro culture media to regulate morphogenesis, callus growth, and organogenesis in plant biotechnology applications.
• Agrochemical Synergy Studies: Investigated for synergistic effects when combined with other agrochemicals (e.g., fertilizers, pesticides) to create integrated crop management solutions.
• Biochemical Synthesis Intermediate: Serves as a sophisticated chiral building block or intermediate for the synthetic elaboration of other bioactive steroidal compounds.
