Common NameTetramethylcyclopentanedione
Description3,3,5,5-Tetramethylcyclopentane-1,2-dione is a tetramethylated derivative of cyclopentane-1,2-dione. It belongs to the class of organic compounds known as cyclic ketones. These are organic compounds containing a ketone that is conjugated to a cyclic moiety. 3,3,5,5-Tetramethylcyclopentane-1,2-dione is one of several structural isomers of tetramethylcyclopentane-1,2-dione wherein four methyl groups are substituted at different positions of cyclopentadione. There are two known isomers of cyclopentanedione including 1,2- and 1,3-cyclopentanedione. They differ at the positions of carbonyl functional groups. Tetramethylcyclopentanediones are found in marijuana (cannabis) smoke. 3,3,5,5-Tetramethylcyclopentane-1,2-dione is formed during the combustion of cannabis ( Ref:DOI ).
