 Zeatin is a plant hormone derived from the purine adenine. It is a member of the plant growth hormone family known as cytokinins. Zeatin was first discovered in immature corn kernels from the genus Zea. Zeatin and derivatives were discovered to be the primary active ingredient in coconut milk, which has long been known to actively induce plant growth.As in the case of kinetin, zeatin has also been reported to have several in vitro anti-aging effects on human skin fibroblasts.
 Zeatin (CAS NO.6025-81-6) is stable under normal temperatures and pressures. It should avoid incompatible materials, and it is incompatibilities with other materials with strong oxidizing agents. The hazardous decomposition products of Zeatin (CAS NO.6025-81-6) are nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, nitrogen.
