CHEMICAL IDENTIFICATION
Product name: Tetramethrin
Chemical name: 3,4,5,6-tetrahydrophthalimidomethyl-(1R,S)-cis,trans-2,2-dimethyl-3-(2-methyl-1-propenyl)cyclopropanecarboxylate
Chemical family: Synthetic Pyrethroids
CAS number: 7696-12-0
Molecular formula: C19H25NO4
Molecular weight: 331.42


PHYSICAL CHEMISTRY
Purity: 95% Min.
Appearance: White crystalline powder.
Odour: Faint characteristic odour.
Melting point: 65-70℃
Boiling point: 185-190℃/13.3Pa
Density: 1.147 g/mL (20℃)
Vapor pressure: 0.0021 Pa (25℃)
Octanol/Water Partition Coefficient: Log Pow = 4.58 (25℃)
Solubility: Easily dissolved in such organic solvents as aromatic hydrocarbon, acetone and ethyl acetate. Be mutually soluble with such synergists as Piperonyl Butoxide and S-421. Solubility in water is 1.83 mg/L (25℃).
Stability: Stable in weak acidic and neutral condition. Easily hydrolyzed in alkaline medium. Sensitive to light. Can be stored over 2 years in normal condition, no corrosion.
 

PROPERTIES
Tetramethrin can quickly knock down mosquitoes, flies and other flying insects and can repel cockroach well. It can drive out cockroach living in dark lift so as to increase the opportunity that cockroach contact insecticide, however, the lethal effect of this product is not so strong; therefore it is often mixed uses with Permethrin with strong lethal effect to aerosol, spray, which are especially suitable for insects prevention for family, public hygiene, food and warehouse. Normally it is used in combination with synergists (e.g. Piperonyl Butoxide), to increase effectiveness.


APPLICATIONS
Aerosol: 0.2% to 0.4% in mixture with lethal insecticides, synergist and emulsifier.
DP: 0.05% to 0.8% in mixture with other insecticides (e.g. beta-cypermethrin, beta-cyfluthrin, deltamethrin, permethrin).
EW: 0.08% to 2% in mixture with other insecticides (e.g. beta-cypermethrin, cypermethrin, d-cyphenothrin, permethrin, rich-d-trans allethrin).
ME: 1% to 4.5% in mixture with other insecticides (e.g. beta-cypermethrin, cypermethrin, permethrin).
SF: 0.1% to 0.3% in mixture with other insecticides (e.g. beta-cypermethrin, permethrin).


TOXICOLOGY
Acute toxicity:
LD50 oral (rat) > 5000 mg/kg;
LD50 dermal (rat) > 2000 mg/kg;
LC50 inhalation (rat) (4 hour) > 2.73 mg/L of air.
(4hr exposure, maximum technically attainable as mist).
Irritancy:
Eye irritancy: Slight irritating.
Skin irritancy: Non irritating.
Sensitisation: Non sensitising.
Long term toxicity: Non teratogenic, non mutagenic, non carcinogenic.
