Usage

General Description

1-DIMETHYLAMINO-2-PENTYNE, also known as DMAP, is a chemical compound that consists of a pentynyl group with a dimethylamino substituent. It is a tertiary amine that is commonly used as a catalyst in organic synthesis reactions, particularly in the acylation of alcohols and amines. DMAP is known for its ability to promote esterification reactions and as a dehydrating agent. It is also used as a base in the cleavage of esters and amides, and as a scavenger for acid byproducts in reactions. DMAP is a colorless liquid with a pungent odor, and it is flammable and potentially hazardous if not handled properly.
