Carboxylic acids are a class of organic compounds characterized by the presence of a carboxyl group (-COOH) attached to an alkyl or aryl group. They play a crucial role in various applications, including pharmaceuticals, agrochemicals, and materials science. Common examples include acetic acid and citric acid. These acids are often used as intermediates in chemical synthesis due to their reactivity with both bases and other functional groups. Their properties, such as acidity and solubility, make them versatile in multiple industrial processes. In the pharmaceutical industry, carboxylic acids serve as building blocks for drug development, enabling the creation of effective medications that target specific biological pathways.
