Understanding the chemical properties and application scope of key reagents is fundamental for any chemist. 7-Octynoic Acid (CAS 10297-09-3) is one such compound that offers significant versatility in various chemical synthesis pathways. Its molecular structure, C8H12O2, includes both a terminal alkyne and a carboxylic acid functional group, making it a valuable building block.

As a direct manufacturer, we highlight that 7-Octynoic Acid is typically supplied as a colorless to light pink liquid with a purity of 99% minimum. This high purity is crucial for its applications in demanding fields. The presence of the terminal alkyne moiety allows it to readily participate in click chemistry reactions, most notably Copper-Catalyzed Azide-Alkyne Cycloaddition (CuAAc). This reaction is highly efficient, selective, and tolerant of many functional groups, making it ideal for bioconjugation, drug discovery, and material science.

A significant application area for 7-Octynoic Acid is in the development of Proteolysis Targeting Chimeras (PROTACs). These molecules are designed to induce the degradation of specific target proteins. The linker region of a PROTAC is critical for its efficacy, and the alkyne group of 7-Octynoic Acid provides a convenient handle for attaching various ligands, contributing to the precise architecture of PROTAC molecules. Researchers looking to buy 7-octynoic acid for this purpose benefit from its reliable performance.

The carboxylic acid functionality of 7-Octynoic Acid also opens up further synthetic possibilities. It can be esterified, amidated, or activated for coupling reactions. This dual reactivity makes it an exceptionally useful intermediate for assembling complex molecular structures. For procurement professionals seeking to purchase 7-octynoic acid, partnering with a reputable supplier in China like ourselves ensures access to consistent quality and competitive price.
