Pesticide Intermediates

Cetic acid is also known as palmitic acid. It is white crystal at room temperature, insoluble in water, and soluble in organic solvents such as ether, chloroform, acetone, etc. Palmitic acid is one of the most widely distributed fatty acids in nature.

It is an important intermediate of pesticide, dye and medicine. Pesticide is the key intermediate of synthesizing new pesticide.

Phenylhydrazine hydrochloride is a kind of solid powder with pink odor and irritant smell at room temperature. It is also a highly toxic substance. It is mainly used in organic intermediates of dye, medicine and pesticide industry. For example, it can produce chromophenol as-g, antipyrine, cationic dye, developer, etc.

Acetyl n-propanol is a chemical substance. It is a colorless and transparent liquid. Soluble in water, ethanol and ether. purpose ：Pharmaceutical intermediate, mainly used for antimalarial chloroquine phosphate. It can also be used to produce vitamin B1, etc.

Acetylacetone is a colorless to light yellow transparent liquid, which is usually a mixture of enol and keto tautomers. The two tautomers are in dynamic equilibrium, with keto form accounting for about 18% and enol form accounting for 82%. Acetylacetone is soluble in water, ethanol, benzene, chloroform, ether, acetone, ethyl acetate and glacial acetic acid. Acetylacetone is an important intermediate in organic synthesis, which is widely used in pharmaceutical, perfume, pesticide and other industries. Acetylacetone is an important raw material in pharmaceutical industry, such as the synthesis of 4,6-dimethylpyrimidine derivatives. Acetylacetone is also used as a solvent for cellulose acetate, a desiccant for paints and varnishes, an additive for fuel oil and lubricating oil, a catalyst, a resin crosslinker, a resin curing accelerator, and an important organic solvent and analytical reagent. Acetylacetone can chelate with cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminum, chromium, iron (Ⅱ), copper and other metal ions due to the presence of enol. Acetylacetone can be used as a metal cleaning agent in micropores by its chelation with metal.
