English Common Name: 6-Benzylaminopurine (6-BAP)
Molecular Formula: C₁₂H₁₁N₅
Molecular Weight: 225.26 g/mol
Structural Features: A cytokinin-type plant growth regulator characterized by a benzylamino group attached to the 6th nitrogen atom of the adenine structure.
Appearance:
Pure form: White crystalline powder.
Industrial-grade: White or pale yellow, odorless.
Melting Point:
Pure product: 235°C (data inconsistency noted; previously reported as 230–233°C).
Solubility:
Poorly soluble in water (60 mg/L at room temperature).
Slightly soluble in ethanol.
Relatively higher solubility in acidic or alkaline solutions.
Stability:
Stable under acidic, alkaline, thermal, and light-exposed conditions.
Safety Profile: Classified as a low-toxicity plant growth regulator, safe for humans and livestock.
Acute Oral LD₅₀:
Rats: 2125 mg/kg (male), 2130 mg/kg (female).
Mice: 1300 mg/kg (both sexes).
Aquatic Toxicity:
48-hour median tolerance limit (TLM) for carp: 12–24 mg/L.
Primarily used to promote cell division, delay senescence, and enhance yield in crops.
Widely applied in agriculture, horticulture, and plant tissue culture.
Handle with standard laboratory precautions despite low toxicity.
Storage: Keep in a cool, dry, and dark environment.
