Proplyl
Proplyl is a term that can refer to a few different chemical concepts, primarily related to organic chemistry. Most commonly, it is used as a synonym for the propyl group, a three-carbon alkyl substituent with the chemical formula -CH2CH2CH3. This group is derived from propane by removing one hydrogen atom. It can attach to other molecules in various ways, leading to isomers. The most common isomer is the n-propyl group, where the attachment is at the end of the three-carbon chain.
Another less common but related usage of "proplyl" can be found in older or more specialized chemical
