The solubility in water at 25 ℃ is 0.3mg/L (pH7), and it is soluble in hydrocarbons, alcohols, ketones, and esters. Stable to light. Stable for at least 1 year below 50 ℃, flash point>113 ℃ (closed cup). Acute oral LD50 in toxic rats>5g/kg. Acute percutaneous LD50 in rabbits>2g/kg. No irritation to rabbit skin and eyes. Moderate allergy to guinea pig skin. Acute inhalation LC50 (4 hours)>5.71g/m3. In the Ames experiment, there was no mutagenic effect. Rats weighing more than 5g/kg have no teratogenic effects. Wild duck acute oral LD50>4640mg/kg. Wild duck and quail LC50>4640mg/kg. In the first generation breeding experiment, the ineffective dose of Chemicalbook was greater than 20mg/kg for quails and 0.1mg/kg for wild ducks, which was harmful to reproduction at 2mg/kg. The LC50 (96 hours) of rainbow trout and wild duck is greater than 1g/L. Water flea LC50 (48 hours) 265.7 μ G/L. Preparation method: CH3 (CH2) 7=CH (CH2) 11COCl and C2H5OMgCH (CO2C2H5) 2 are refluxed in benzene to generate (Z) - CH3 (CH2) CH=CH (CH2) 11COCH (CO2C2H5) 2. The compound is hydrolyzed and decarboxylated in 4:1 acetic acid hydrochloric acid reflux to generate (Z) - CH3 (CH2) CH=CH (CH2) 11COCH2, which is finally reacted with hydrazine hydrate and potassium hydroxide solution to obtain this product. Used as a sexual attractant for female and male houseflies, interfering with mating, sometimes mixed as a poison and insecticide
