Description:

Alpha-Cypermethrin is a synthetic pyrethroid insecticide with high potency and rapid knockdown effect against a broad spectrum of insects. It is an enriched isomer of cypermethrin, offering higher biological activity at lower doses. Alpha-cypermethrin is used in agriculture, public health, and household pest control.

Physical and Chemical Properties:

• Appearance: Off-white to light beige crystalline powder

• Odor: Slight aromatic odor

• Melting Point: 78–82°C

• Solubility: Practically insoluble in water; soluble in acetone, xylene, and hexane

• Stability: Stable under normal storage; decomposes under strong acidic or basic conditions

Specification Parameters:

• Purity (GC): ≥97.0%

• Moisture Content: ≤0.5%

• Acidity (as H2SO4): ≤0.2%
