Sodium 4-pentynoate

Sodium 4-pentynoate is a alkynylacetate analogue, can be metabolically incorporated onto cellular proteins through biosynthetic mechanisms for profiling of acetylated proteins in diverse cell types[1]. Sodium 4-pentynoate is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
