5-Bromo-2-methylbenzaldehyde(CAS: 90050-59-2)

5-Bromo-2-methylbenzaldehyde is a crystalline solid with a molecular weight of approximately 192.04 g/mol. It is slightly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but can undergo electrophilic aromatic substitution reactions due to the presence of the bromine substituent.

5-Bromo-2-methylbenzaldehyde is typically synthesized by the bromination of 2-methylbenzaldehyde using bromine in the presence of a Lewis acid like aluminum bromide. The reaction is highly selective and yields a high percentage of the desired product.

5-Bromo-2-methylbenzaldehyde is used in the pharmaceutical industry for the synthesis of various organic compounds and intermediates. It is also utilized in the polymer industry for the production of certain polymers and in the sensor industry for developing gas detection devices.

When handling 5-Bromo-2-methylbenzaldehyde, it is important to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. It should be handled in a well-ventilated area or fume hood to minimize inhalation risk. In case of a spill, immediately clean up using appropriate absorbent materials and follow the safety data sheet (SDS) for disposal guidelines.
