What is Indole-3-Butyric acid CAS 133-32-4?
Indole-3-butyric acid, as an efficient plant rooting agent, is widely used in agricultural seedling raising and has both low toxicity and environmental compatibility. Its potassium salt derivatives further optimize water solubility and safety. When in use, strictly follow the concentration specifications and avoid contact with strong oxidants or high-temperature environments.
