The Uses of 6-Heptynoic acid
6-Heptynoic acid is used as a precursor for the the preparation of boradiazaindacenes (BODIPY dyes) by reacting with oxalylchloirde. It is used to prepare 4,4-difluoro-8-(hept-6-yne)-3,5-di(2-(4-methoxyphenyl))-4-bora-3a,4a-diaza-sindacene by reacting with 2-(4-methoxyphenyl)-1H-pyrrole.
Definition
ChEBI: 6-heptynoic acid is a medium-chain fatty acid.
General Description
6-Heptynoic acid is an alkynoic acid with an acetylene bond. It undergoes condensation with various pyrroles to afford optical diverse fluorescent dyes with a terminal alkyne.
