Key benefits
- Powerful Cytokinin Bioactivity: As a high-potency phenylurea cytokinin, CPPU exhibits up to 10–100 times higher biological activity than classic purine cytokinins (like 6-BA or Kinetin) in stimulating plant cell division and expansion.
- Rapid Fruit & Berry Enlargement: Dramatically increases cell number and cell size, leading to significant fruit expansion, uniform berry development, and weight increase in kiwi, seedless grapes, melons, and navel oranges.
- Enhances Fruit Set & Prevents Physiological Drop: Significantly boosts fruit setting rates, reduces physiological fruit and flower drop, and preserves structural fruit firmness for better field retention.
- Synergistic Formulation Flexibility: Combines effectively with Gibberellic Acid (GA3) and Auxins (NAA/IBA) in commercial formulations to achieve synergistic fruit enlargement while preventing fruit hollowiness or rind cracking.
- Extends Post-Harvest Shelf Life: Delays chlorophyll breakdown and senescent degradation, helping harvested fruits and green vegetables maintain freshness, color, and marketability during transport and cold storage.
Suggested dosage & application
For formulators
TC grade; formulate into SL/SP. CPPU 98% TC is insoluble in water but highly soluble in ethanol or acetone, typically formulated into 0.1% or 1% SL or soluble powders. It is extremely stable, but proper wetting agents are needed to prevent active-ingredient precipitation upon field dilution. Every shipment includes a batch COA.
For direct field use (precise dosing is essential)
Kiwifruit: 5–20 mg/L at 20–25 days after full bloom. Grapes: 5–10 mg/L at 10–15 days post-bloom. Melons/cucumbers: 10–20 mg/L on ovaries at blooming. Over-dosing causes fruit distortion or splitting.

Frequently asked questions
01What is the CAS number of forchlorfenuron (CPPU)?
CPPU (forchlorfenuron, KT-30) has CAS number 68157-60-8. We supply 98% technical grade (TC) powder with a batch COA for every shipment.
02What does CPPU do, and at what rates is it used?
CPPU is a highly active phenylurea PGR that accelerates cell division, differentiation and elongation — markedly increasing fruit set and enlargement. Precise dosing is essential (typically 5–20 mg/L): kiwifruit 5–20 mg/L at 20–25 days after full bloom; grapes 5–10 mg/L at 10–15 days post-bloom; melons/cucumbers 10–20 mg/L on ovaries at blooming. Over-dosing causes fruit distortion or splitting.
03Is this a ready-to-use product or a technical-grade material?
It is a TC grade for formulators; formulate into SL/SP. CPPU 98% TC is insoluble in water but highly soluble in ethanol or acetone, typically formulated into 0.1% or 1% SL or soluble powders. It is extremely stable, but proper wetting agents are needed to prevent active-ingredient precipitation upon field dilution.
04Can CPPU be blended with other PGRs?
Yes. It is often co-formulated with gibberellic acid (GA3): GA3 elongates cells while CPPU accelerates cell division, maximizing fruit size without deformation.
05What is the MOQ, lead time and shelf life?
MOQ is 25 kg. Typical lead time is about 10 working days to Shanghai port; OEM packaging and batch COA are available. Shelf life is 24 months in the original sealed packaging.
