Amitraz, in its pure form, is a white monoclinic or needle-like crystal with a melting point of 86-87°C, a boiling point of approximately 450.7°C (760 mmHg), a density of approximately 0.98-1.0 g/cm³, a flash point of approximately 226.4°C, and a vapor pressure of approximately 0.0 ± 1.1 mmHg (25°C). Amitraz is soluble in organic solvents such as acetone, xylene, and methanol, but has low solubility in water (approximately 1 mg/L).
Amitraz is stable at room temperature and pressure, and relatively stable under neutral or alkaline conditions. At 20°C, its half-life in water at pH 7 is 6 hours. Amitraz is unstable in acidic media and will slowly decompose and deteriorate if stored in a humid environment for an extended period.
Amitraz solution is a pale yellow, clear liquid prepared by adding suitable emulsifiers and solvents to amitraz. Its emulsifying properties must meet the requirements, and the moisture content is usually not higher than 0.15%.
