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-Propylpyrazole is a non-classical inhibitor of aldehyde oxidase that has been shown to have an inhibitory effect on pentane. 1-Propylpyrazole has peroxidase-like activity, which means it can bind to lipid hydroperoxides in the presence of hydrogen peroxide or peroxidase. It has also been shown to be an effective inhibitor of dehydrogenase, which is an enzyme that catalyzes the oxidation of aldehydes and ketones to carboxylic acids. This drug is not active against classical aldehyde oxidases such as alcohol dehydrogenase, but it does inhibit polyunsaturated fatty acid synthesis by binding with cytochrome P450 enzymes.

2-Allylcyclohexanone is an unsaturated ketone that is synthesized by the ring-opening of allyl cyclohexane carboxylate with sodium hydroxide. It can be used as a chemical intermediate for the synthesis of other compounds. 2-Allylcyclohexanone can also be used to react with hydroxide solution to produce a salt and an alcohol. The hydroxide solution can act as a base, reducing the carbonyl group in the presence of an acid to form the corresponding alcohol. This reaction is stereoselective because it only occurs when there are two different groups on adjacent carbons.
2-Allylcyclohexanone has been shown to inhibit non-nucleoside reverse transcriptase inhibitors (NNRTIs) such as nevirapine, efavirenz, and delavirdine. In addition, it has been found to have functional groups that are capable of reacting

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.
