Chemical Structure

Basic Info
Butanethiol has a molecular formula C4H10S. Its CAS number is 109-79-5. The chemical formula is CH3CH2CH2CH2SH.
Butanethiol has a skunk or garlic-like odor. It is colorless, easily flowing and has a low viscosity. It is flammable and has a thiol smell. It is also soluble in alcohols, ethers, hydrogen sulfide, and water, but only slightly. Butanethiol decomposes under alkaline conditions and decomposition speeds up with temperature. Butanethiol can also oxidize, so keep it away from oxidants and in a shaded, sealed area.
It has a scent similar to that of fat, stewed meat, soft boiled onions and eggs. Chemicalbook states that the boiling point is between 97 and 98.4. It is slightly soluble (0.6g/100m1) in oil and water, but not soluble with ethanol. Cheese, boiled eggs or beef (fried, boiled, or boiled), and beer are all natural products.

Product Packaging

Butanethiol was one of the first varieties of the low-carbon thiol family, and it was used to odorize coal gas and natural gas. Butyl mercaptan is a synthetic pesticide that has gained popularity in recent years.
Butanethiol, an intermediate in the synthesis for various pesticides, such as organophosphates, is also widely used as a polymerization reaction controller, stabilizer and other applications. In China, there are reports about the preparation of tert-butyl-mercaptan (TMM), methyl-mercaptan (EM), ethyl-mercaptan (EME) and dodecanethiol. However, there are no reports or manufacturers of n butanethiol. Their products are entirely imported. Butanethiol development in China is still blank.
Butanethiol is used to odorize natural gas, coal gas and other gases. Add C3-C4 mercaptan alkyl to gas in order to prevent gas leakage accidents, such as fires, explosions, and poisoning.
Butanethiol, an intermediate used in the production of pesticides like organophosphates or thioamino acids esters is also highly demanded. Butyl mercaptan will be in high demand as an intermediate in the synthesis for various pesticides, such as organophosphates, thioamino acids esters and other.
Butanethiol is a widely used solvent, polymerization regulator, stabilizer, surfactant and food flavoring. It has good market prospects.
