3-Bromo-2-ethylbenzoic acid(CAS: 99548-72-8)

3-Bromo-2-ethylbenzoic acid (CAS: 99548-72-8) is a crystalline solid with a molecular weight of 227.02 g/mol. It has a melting point of 121-122°C and is only slightly soluble in water but more soluble in organic solvents like ethanol and acetone. Chemically, it is highly reactive due to the presence of a carboxylic acid group and a bromine substituent, making it suitable for a variety of chemical reactions such as esterification and substitution reactions.

3-Bromo-2-ethylbenzoic acid is typically synthesized via bromination of 2-ethylbenzoic acid. This involves reacting 2-ethylbenzoic acid with bromine in the presence of a Lewis acid catalyst like aluminum bromide. The reaction is usually conducted in an inert solvent such as dichloromethane, and the yield is typically around 80-85%. The selectivity towards the brominated product is high, making this a reliable method for its synthesis.

3-Bromo-2-ethylbenzoic acid (CAS: 99548-72-8) is used in various industries. It is particularly important in the pharmaceutical industry as a precursor for the synthesis of certain drugs. Additionally, it finds applications in the polymer industry for modifying the properties of polymers, and in the sensor industry due to its reactivity. Its use in semiconductors is less common but can be relevant in specialized applications.

When handling 3-Bromo-2-ethylbenzoic acid (CAS: 99548-72-8), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a laboratory coat. The compound should be handled in a well-ventilated area or a fume hood to minimize inhalation risk. Spills should be contained and cleaned up using absorbent materials followed by thorough washing with water. Safety data sheets (SDS) should be consulted for detailed handling and emergency procedures.
