2,5-Dimethylbenzaldehyde(CAS: 5779-94-2)

2,5-Dimethylbenzaldehyde is a colorless to light yellow liquid with a boiling point of 210.5°C and a melting point of 22°C. Its molecular weight is approximately 128.16 g/mol. It is slightly soluble in water but miscible with organic solvents like ethanol and ether. This compound is known for its reactivity towards nucleophiles and electrophiles, making it a useful reagent in organic synthesis.

2,5-Dimethylbenzaldehyde can be synthesized via the reduction of 2,5-dimethylbenzoyl chloride with sodium borohydride. Another method involves the alkylation of benzaldehyde with methyl iodide followed by hydrogenation to remove the terminal double bond. These processes yield a high purity product with good selectivity and yield.

2,5-Dimethylbenzaldehyde finds applications in the pharmaceutical industry for the synthesis of certain drugs, in the polymer industry as a monomer or additive, in the sensor industry for gas detection, and in the semiconductor industry as a precursor for organic semiconductor materials. Its versatile reactivity and functional groups make it suitable for various applications.

When handling 2,5-Dimethylbenzaldehyde, it is important to wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be handled by containing them and neutralizing with a suitable base before cleaning up. Always consult the Material Safety Data Sheet (MSDS) for detailed safety information and guidelines.
