Kinetin 99% TC, chemically known as 6-Furfurylaminopurine, is a cytokinin plant growth regulator supplied as a technical raw powder for plant tissue culture, seed treatment, ornamental applications, and selected agricultural formulations.
The product is supplied as a white crystalline powder and is standardized to an assay of not less than 99% by HPLC. Kinetin belongs to the cytokinin group of plant growth regulators and is primarily associated with cell division, bud differentiation, shoot development, and regulation of plant tissue senescence.
Plant tissue culture is one of the principal technical applications of Kinetin. It can be incorporated into culture media to regulate shoot induction and organ differentiation. When combined with auxin-type plant growth regulators, the cytokinin-to-auxin ratio can influence the balance between shoot and root development.
Kinetin is also relevant to formulations intended for delaying leaf or tissue senescence, maintaining plant tissue condition, seed treatment, and selected flower-preservation applications. The actual response depends strongly on concentration, plant species, developmental stage, and the presence of other plant growth regulators.
The technical material is only slightly soluble in water. It can be dissolved in suitable dilute acid or alkali systems and selected organic solvents such as and DMSO. Appropriate formulation methods are therefore required for preparation of concentrated solutions and water-dilutable products.

Kinetin is a classic cytokinin compound used to regulate plant developmental processes associated with cell division and organ differentiation.
Its technical relevance is particularly strong in tissue culture systems, where cytokinin activity is used to stimulate shoot formation and bud development. Kinetin can be applied alone or together with auxins depending on the desired morphogenic response.
The ratio between cytokinin and auxin is an important formulation factor in plant tissue culture. Higher cytokinin relative to auxin is generally associated with shoot-oriented responses, while different balances can shift organ differentiation toward other developmental outcomes. The appropriate ratio should be established for the target plant species and culture stage.
Kinetin is also associated with delayed plant tissue senescence. This characteristic makes it relevant to selected applications involving maintenance of leaf condition, ornamental plant quality, and flower-preservation systems.
The material is only slightly soluble in water, so formulation development should account for its solubility profile. Dilute acid or alkali systems, DMSO, or other suitable formulation approaches may be used according to the intended application.
Because Kinetin is biologically active at relatively low concentrations, accurate weighing and homogeneous distribution are important. Excessive concentration can lead to abnormal plant growth or undesired morphological responses.
Kinetin is widely used as a cytokinin component in plant tissue culture media.
It can be incorporated into propagation systems where bud induction, shoot multiplication, or organ differentiation is required.
The appropriate concentration depends on plant species, explant type, basal medium, culture stage, and the concentration of auxins or other growth regulators used in the same system.
Kinetin can be used in formulations or culture systems intended to promote bud differentiation and shoot development.
Its cytokinin activity makes it relevant where activation of shoot-related development is a primary objective.
Concentration control is important because different plant species can respond differently to the same Kinetin level.
Kinetin is associated with regulation of senescence-related processes in plant tissues.
This property can be considered in selected ornamental, flower-preservation, and plant-quality formulations where maintenance of tissue condition is an important objective.
The actual persistence of the response depends on plant material, concentration, temperature, storage conditions, and the overall treatment system.
Kinetin can be incorporated into selected seed-treatment formulations.
Relevant formulation objectives may include regulation of dormancy-related processes and early seedling development. Appropriate concentrations should be established according to crop species and seed characteristics.
Kinetin is frequently combined with auxin-type plant growth regulators in tissue culture and propagation systems.
The combination provides a method for adjusting the balance between shoot and root differentiation. Different auxins and different concentration ratios can generate different developmental responses.
Formulation design should therefore consider both the individual concentration of Kinetin and the ratio between cytokinin and auxin.
Kinetin is commonly considered for high-value crop, propagation, tissue-culture, and ornamental applications where precise hormonal control is required.
Compared with broad agricultural use PGRs, Kinetin is more often selected for technically controlled systems in which cytokinin concentration and organ differentiation are key formulation parameters.

Kinetin 99% TC is standardized to contain not less than 99% 6-Furfurylaminopurine, with active content determined by HPLC. Loss on drying is specified at not more than 0.5%, while residue on ignition is specified at not more than 0.1%.
The technical material is supplied as a white crystalline powder and has CAS number 525-79-1.
Kinetin is slightly soluble in water and soluble in suitable dilute acid, dilute alkali,and DMSO systems. These solubility characteristics should be considered when preparing tissue-culture stock solutions, concentrated agricultural formulations, or other liquid products.
Quality documentation includes a Certificate of Analysis and Safety Data Sheet. Batch-specific assay, loss on drying, residue on ignition, appearance, and other applicable parameters should be verified against the corresponding COA.
The material should be kept in tightly sealed packaging under cool, dry, and shaded storage conditions. Excessive heat and strongly alkaline environments should be avoided.
Kinetin 99% TC is a technical plant growth regulator material. Agricultural registration status, permitted crops, application concentrations, treatment methods, residue requirements, and labeling conditions vary by jurisdiction. Finished agricultural products should comply with the applicable requirements of the intended market.
