Potassium thioacetate is widely used as a sulfur source in the synthesis of sulfur-containing organic compounds. Potassium thioacetate is mainly used in the synthesis of heterocyclic compounds, polymers, transition metal ligands, nanoparticles, bioactive molecules and complexes containing macromolecules.

Isopropyl ether is a good solvent for animal, vegetable and mineral oils, which can be used to extract nicotine from tobacco; It is also a good solvent for paraffin and resin.Isopropyl ether is often mixed with other solvents in the dewaxing process of paraffin based oil. As a solvent, diisopropyl ether is also used in pharmacy, smokeless powder, coating and paint cleaning. Isopropyl ether has high octane number and frost resistance, and can be used as gasoline admixture. This product is easy to form peroxide, which will explode when shaking. P-benzylaminophenol is often added as stabilizer. The anesthetic effect of Isopropyl ether is lighter than that of ether, but the duration of anesthesia is longer.

1,3-phenylenediamine appears as colorless or white colored needles that turn red or purple in air. Melting point 64-66 C. Density 1.14 g / cm3. Flash point 280 F. May irritate skin and eyes. Toxic by skin absorption, inhalation or ingestion. Used in aramid fiber manufacture, as a polymer additive, dye manufacturing, as a laboratory reagent, and in photography.

Cyanuric chloride is a white crystal with strong irritating chlorine smell, corrosive to skin, irritating and tear inducing to eyes, soluble in anhydrous ethanol, ether, chloroform, acetic acid and acrylonitrile, and insoluble in cold water. Cyanuric chloride is an important intermediate in the production of highly efficient and low toxic triazine herbicides and insecticides, as well as in the production of fluorescent brightener, polyester and other reactive dyes for synthetic fiber dyeing. It is also used in the production of synthetic resin, rubber, polymer antioxidant, explosive, fabric shrinkable agent, surfactant, etc.

Ethyl oleate is a fatty acid ester formed by the condensation of oleic acid and ethanol. It is a colorless to light yellow liquid. Ethyl oleate is produced by the body during ethanol intoxication. Ethyl oleate is used as a solvent for pharmaceutical drug preparations involving lipophilic substances such as steroids. It also finds use as a lubricant and a plasticizer. Ethyl oleate is regulated as a food additive by the Food and Drug Administration under "Food Additives Permitted for Direct Addition to Food for Human Consumption", 21CFR172.515. Ethyl oleate has been identified as a primer pheromone in honeybees. Ethyl oleate is one of the fatty acid ethyl esters (FAEE) that is formed in the body after ingestion of ethanol. There is a growing body of research literature that implicates FAEEs such as ethyl oleate as the toxic mediators of ethanol in the body (pancreas, liver, heart, and brain). Among the speculations is that ethyl oleate may be the toxic mediator of alcohol in fetal alcohol syndrome. The oral ingestion of ethyl oleate has been carefully studied and due to rapid degradation in the digestive tract it appears safe for oral ingestion. Ethyl oleate is not currently approved by the U.S. Food and Drug Administration for any injectable use. However, it is used by compounding pharmacies as a vehicle for intramuscular drug delivery, in some cases to prepare the daily doses of progesterone in support of pregnancy. Studies which document the safe use of ethyl oleate in pregnancy for both the mother and the fetus have never been performed.
