Forchlorfenuron (Cat No.: R054716) is a synthetic plant growth regulator with the molecular formula C₁₂H₁₀ClN₃O. It belongs to the phenylurea class and promotes cell division and elongation by mimicking cytokinin activity. Commonly used in horticulture, it enhances fruit size, yield, and shelf life in crops like grapes, kiwifruit, and melons. Forchlorfenuron is applied during early fruit development stages to stimulate growth. While effective, its usage must be carefully managed to avoid overgrowth or quality issues. It is regulated in some regions due to residue concerns.
