Identity of Kinetin
6-Furfurylaminopurine has a CAS number of 525-79-1 and a molecular formula of C10H9N5O with a molecular weight of about 251.67. It is classified as a general chemical and can be used as a biochemical reagent and a plant hormone. Kinetin is the common name of the compound, and it is one of the most studied members of the cytokinin family, the plant hormones responsible for cell division and growth regulation.
Mode of Action
Kinetin is used as a plant growth hormone that induces the nuclear division of plant cells. Cytokinins act by promoting the progression of the cell cycle, and kinetin specifically supports the division of cells in culture and in intact plants. This activity is the basis of its use in tissue culture, where it maintains the dividing state of explants, and in agriculture, where it stimulates growth responses in treated crops. Its action is synergistic with auxins, and the balance between the two hormone classes controls the developmental outcome.
Use for Storage Life Extension
Kinetin is used for root crops to prolong the storage life, prevent water loss and maintain green color by spraying before harvest or soaking after harvest. The hormone delays senescence: it slows the degradation of chlorophyll and proteins, so treated produce stays green and firm longer. For leafy vegetables, tubers and ornamental products, this post-harvest treatment reduces losses during storage and transport, and it is a practical application of the anti-senescence property of cytokinins.
Use in Research and Biotechnology
In plant research, kinetin is a standard biochemical reagent for studying cell division, senescence and hormone signaling. It is used in culture media for plant propagation, in experiments on callus induction and organogenesis, and in studies of the molecular mechanisms of cytokinin action. The defined purity of the reagent grade is important for reproducible results, and it is supplied with the certificate of analysis.
Handling and Application
Kinetin is handled as a laboratory and agricultural chemical. For tissue culture, it is dissolved in dilute alkali or acid and added to the medium at the defined concentration; for agricultural use, it is formulated into sprays or dips at the registered rate. Protective equipment and good hygiene are recommended during handling, and the product should be stored in a cool, dry place away from light and moisture.
