5-Bromo-3-fluoro-2-hydroxybenzaldehyde(CAS: 251300-28-4)

5-Bromo-3-fluoro-2-hydroxybenzaldehyde is a crystalline solid with a molecular weight of 239.04 g/mol. It is slightly soluble in water and more soluble in organic solvents like ethanol and acetone. Chemically, it is a chromophoric compound, meaning it absorbs light in the ultraviolet and visible regions, making it useful for spectroscopic analysis. It is moderately reactive, particularly towards nucleophiles and reducing agents.

5-Bromo-3-fluoro-2-hydroxybenzaldehyde is typically synthesized through the bromination of 3-fluoro-2-hydroxybenzaldehyde followed by purification. Commonly, this involves the use of bromine in the presence of a Lewis acid catalyst such as aluminum bromide. The reaction is carried out under anhydrous conditions to ensure high selectivity and yield. The product is then isolated and purified using standard techniques like recrystallization.

5-Bromo-3-fluoro-2-hydroxybenzaldehyde is primarily used in the pharmaceutical industry for the synthesis of various drug intermediates. It also finds applications in the polymer industry for the development of new materials with enhanced properties. Additionally, it is used in the sensor industry for the fabrication of sensors that can detect specific analytes. Its use in semiconductors is less common but can be relevant in special applications requiring high purity.

When handling 5-Bromo-3-fluoro-2-hydroxybenzaldehyde, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate absorbent materials and followed by the application of a neutralizing agent if necessary. Always consult the Safety Data Sheet (SDS) for specific handling and disposal guidelines. Due to its reactivity, avoid contact with reducing agents and strong bases.
