Methyl 4-ethynylbenzoate (CAS: 102569-84-8) is a specialized organic intermediate defined by its acetylenic functionality attached to an esterified aromatic ring. Produced via Sonogashira coupling or alkyne addition, it serves as a critical building block in pharmaceutical synthesis and materials science.
Store under inert atmosphere at controlled temperatures to prevent polymerization. Handle with PPE due to potential skin irritation and flammability risks associated with terminal alkynes.
