What is another name for a benzyl group?

Published in Chemical Group 2 mins read

A common alternative name for a benzyl group is phenylmethyl. This organic functional group is derived from toluene, where a hydrogen atom from the methyl group is removed. It consists of a phenyl group (C₆H₅–) attached to a methylene group (–CH₂–).

The benzyl group is frequently encountered in organic chemistry, often serving as a protecting group for alcohols, amines, and carboxylic acids due to its stability and ease of removal under specific conditions. It also forms a crucial part of the structure of certain biomolecules.
