3-Methylthiophene-2-carboxylic acid (CAS: 1007-64-9, C6H6O2S) is a heterocyclic intermediate synthesized via Vilsmeier-Haack formylation or direct carboxylation of methylthiophene derivatives. It serves as a critical building block in organic synthesis.
Store under inert atmosphere at temperatures below 5°C to prevent polymerization. Use appropriate PPE including nitrile gloves and safety goggles due to potential skin irritation and respiratory hazards during handling.
