Putrescine is a polyamine plant growth regulator affecting the synthesis of macromolecules. Promotes adventitious root formation. Precursor of spermidine.

Methanethiol is a compound that occurs naturally in the environment. It is used as a fungicide, insecticide and herbicide. Methanethiol inhibits the growth of microorganisms by binding to metal ions on the surface of cells. This prevents DNA replication and protein synthesis, leading to cell death. Methanethiol also has anti-inflammatory properties which may be due to its ability to inhibit adenosine A1 receptor activity in humans.

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%.
