Zeatin (trans-Zeatin) 98% Powder
Zeatin 98% natural cytokinin for formulators; formulate into SL/SP
Zeatin (trans-Zeatin) 98% Powder, CAS 1637-39-4, is a highly potent natural cytokinin: it stimulates rapid cell division, shoot initiation and lateral bud development, and delays leaf senescence while enhancing chlorophyll retention. Ultra-low rates — overall range 0.1–1 mg/L. TC grade for formulators; formulate into SL/SP (0.01–0.1% SL or SP; highly stable at neutral pH). MOQ 10g; lead time about 5 working days leaving by air; OEM and batch COA available; 24-month shelf life.

Key benefits
- Ultra-High Bioactivity Natural Cytokinin: As the most bioactive endogenous adenine-type cytokinin, trans-Zeatin 98% TC regulates plant cell division, tissue differentiation, and organogenesis at extremely low active concentrations.
- Essential for Plant Tissue Culture & Micropropagation: Serves as the golden-standard plant growth regulator in high-end tissue culture media (such as MS media) to induce adventitious shoot formation and somatic embryogenesis.
- Delays Leaf Senescence & Preserves Chlorophyll: Effectively inhibits chlorophyll degradation and protein breakdown in leaf tissues, significantly extending green leaf longevity, photosynthetic efficiency, and post-harvest shelf life.
- Breaks Apical Dominance & Stimulates Lateral Bud Growth: Counteracts auxin-driven apical dominance to promote lateral bud sprouting, stem branching, and tiller development for optimized canopy density and flower bud differentiation.
- Enhances Nutrient Transport & Abiotic Stress Recovery: Directs sink-source nutrient allocation toward developing fruits, shoots, and young leaves while mitigating physiological stress caused by thermal or drought conditions.
Suggested dosage & application
For formulators
TC grade; formulate into SL/SP. Zeatin 98% is poorly soluble in cold water but dissolves easily in dilute acids, alkalis or ethanol, and is typically formulated into 0.01% to 0.1% SL or SP. It is highly stable at neutral pH. Every shipment includes a batch COA.
For direct field use (ultra-low rates)
Seedling vigor: 0.1–0.2 mg/L. Budding and full bloom for fruit set: 0.5–1 mg/L. Before or after weather extremes: 0.2–0.5 mg/L. Overall range: 0.1–1 mg/L.

Frequently asked questions
01What is the CAS number of zeatin?
trans-Zeatin has CAS number 1637-39-4. We supply 98% powder with a batch COA for every shipment.
02What does zeatin do, and at what rates is it used?
Zeatin is a highly potent natural cytokinin: it stimulates rapid cell division, shoot initiation and lateral bud development, and delays leaf senescence while enhancing chlorophyll retention. Because of its ultra-high natural activity, field rates are extremely low: 0.1–0.2 mg/L for seedling vigor, 0.5–1 mg/L at budding and full bloom for fruit set, and 0.2–0.5 mg/L before or after weather extremes — overall range 0.1–1 mg/L.
03Is this a ready-to-use product or a technical-grade material?
It is a TC grade for formulators; formulate into SL/SP. Zeatin 98% is poorly soluble in cold water but dissolves easily in dilute acids, alkalis or ethanol, and is typically formulated into 0.01% to 0.1% SL or SP. It is highly stable at neutral pH.
04Can zeatin be blended with other materials?
Yes. It pairs exceptionally well with fulvic acid or amino acid matrices for premium biostimulant lines, and is co-formulated with low doses of auxins (IBA/NAA) to balance rapid root initiation with strong shoot development.
05What is the MOQ, lead time and shelf life?
MOQ is 10g. Typical lead time about 5 working days leaving from China by air; OEM packaging and batch COA are available. Shelf life is 24 months in the original sealed packaging.
