S 3304 is primarily used in agricultural research and practices as a plant growth regulator. It helps in studying the effects of brassinosteroids, a class of plant hormones, on plant development and stress responses. By modulating these hormones, it aids in enhancing crop yield, improving stress tolerance, and promoting healthier plant growth. Researchers also utilize it to understand the molecular mechanisms behind plant hormone signaling, contributing to advancements in sustainable agriculture and crop improvement strategies.
