Phenylhydrazine is a white crystalline solid with a molecular weight of 150.25, and the molecular formula C6H5NHN. It is soluble in water, alcohol, ether and chloroform. Phenylhydrazine can react with an acid chloride to form a hydrazone; this reaction is used in the synthesis of some pharmaceuticals. The most common use of phenylhydrazine is as a precursor to various pharmaceuticals, such as antipyretics and anti-inflammatory agents. Phenylhydrazine reacts with zinc chloride to form 1-(5-methyl-1H-pyrazol-4-yl)ethanone.

1-Monotetranoin is a fatty ester that is involved in the process of lipolysis, which is the breakdown of fat cells. Lipolysis occurs when an enzyme called lipase hydrolyzes triglycerides into glycerol and three fatty acids. 1-Monotetranoin has been shown to be a potent stimulator of growth factor production and cell proliferation in vivo models. It has also been shown to be effective at inhibiting angiogenic processes in vitro, including the release of growth factors from fat cells. The neutral pH optimum for 1-monotetranoin is between 7 and 8, which may be due to its hydrophobic nature.

2-Bromo-3,3,3-trifluoro-1-propene is a chemical compound that has been synthesized in an asymmetric reaction. The reactant is bromopropane and the product is 2,2,2-trifluoropropene. The methylene group on the propene molecule is activated by the nucleophilic attack of a fluoride ion from hydrogen fluoride to form a cavity with a highly strained bond. The kinetic study of this reaction revealed that the activation energy for the reaction is 42 kJ/mol. Palladium-catalyzed coupling reactions are catalyzed by palladium and require nonpolar solvents such as toluene or dichloromethane. This type of reaction has been shown to be exothermic with an isolated yield of 1%.

Piperyline is an alkanoic acid that has shown to be effective against skin cancer. It also has antimicrobial properties, which may be due to its ability to bind metal ions and form polymeric compounds. Piperyline inhibits microbial growth by inhibiting the synthesis of proteins and nucleic acids. The antimicrobial activity is related to its cationic polymerization with hydroxyl groups, which forms a structure that can inhibit microbial enzymes and disrupt microbial cell membranes. This compound also interacts with the skin's natural lipids, making it difficult for microorganisms to attach and grow on the skin. Piperyline is synthesized in organic chemistry laboratories as an amide precursor of other pharmaceuticals such as penicillin.
