3,4-Dimethylthiophene(CAS: 632-15-5)

3,4-Dimethylthiophene (CAS: 632-15-5) is a colorless liquid with a characteristic odor. It has a molecular weight of approximately 116.17 g/mol. The compound is slightly soluble in water and miscible with common organic solvents. It is relatively stable but can react with strong oxidizers. It has a boiling point of 152°C and a melting point of -100°C.

3,4-Dimethylthiophene can be synthesized via the Friedel-Crafts alkylation of thiophene with methylbenzene in the presence of Lewis acids such as aluminum chloride. Alternatively, it can be produced through the hydrodesulfurization of dimethylbenzothiophene. The yield is highly dependent on the reaction conditions and catalysts used.

3,4-Dimethylthiophene (CAS: 632-15-5) is used in the production of various chemicals, including diesel desulfurization, pharmaceuticals, and as a precursor in the synthesis of aryl sulfides and other thiophene derivatives. It is also utilized in the manufacturing of polymers and as a component in sensor technology.

When handling 3,4-Dimethylthiophene (CAS: 632-15-5), it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be immediately contained and cleaned up using appropriate absorbent materials. Refer to the Safety Data Sheet (SDS) for detailed emergency procedures and storage guidelines.
