Formula: C19H30O5
Molecular Weight: 338.43
Boiling Point:180℃/133.3Pa
Description:
Quality Index:
Content：≥95%
Moisture:≤0.2%
Acid degree:≤0.15%
Test Standard:Q/ZSKZ 031
Solubility:insoluble in water, but soluble in many organic solvents including mineral oil and dichloro-methane.

Toxicity:Acute oral LD50 to rats is more than 11500mg/kg.Acute oral LD50 to rabbits is 1880mg/kg.The long-term safe absorption amount for men is 42ppm.
Application：
Piperonyl butoxide is a synergist to increase pesticide effectiveness. It especially for synthetic pyrethroids.Its dosage is 5-10 times of pyrethroid and this can obviously increase pyrethroid's effect 3 times. If formulate it with cypermethrin, tetramethrin, permethrin, deltamethrin, cyholothrin, and fenalerate, the synergism is remarkable.
