3-(4-bromophenyl)-2-(tert-butoxycarbonyl)propanoic acid; CAS No.: 132153-48-1; 3-(4-bromophenyl)-2-(tert-butoxycarbonyl)propanoic acid. PROPERTIES: This compound appears as a white crystalline powder with molecular formula C14H15BrNO4 and a molecular weight of 327.18 g/mol. It demonstrates a melting point in the range of 152-156 C and shows moderate solubility in common organic solvents like methanol and ethyl acetate. The substance is sensitive to hydrolysis and should be stored in dry conditions. Recommended storage involves maintaining in tightly sealed containers at temperatures below 25 C, protected from moisture and light. When handling, standard laboratory safety protocols should be followed, including the use of protective gloves and eye wear, as 3-(4-bromophenyl)-2-(tert-butoxycarbonyl)propanoic acid may cause skin irritation. The carboxylic acid group requires careful handling in strongly basic environments. APPLICATIONS: In the pharmaceutical industry, 3-(4-bromophenyl)-2-(tert-butoxycarbonyl)propanoic acid serves as an intermediate for synthesizing non-steroidal anti-inflammatory drugs (NSAIDs), as described in medicinal chemistry literature focusing on propanoic acid derivatives. Its bromo substituent enables participation in cross-coupling reactions for constructing biaryl systems. Additionally, this compound functions as a building block for preparing agrochemicals with fungicidal activities through coupling reactions. Academic research has explored its potential in metal coordination chemistry for creating luminescent sensors, as reported in inorganic chemistry journals. The propanoic acid framework also facilitates formation of metal-organic frameworks (MOFs), making it valuable for gas storage applications in materials science, as evidenced by studies in crystallography publications.
