3,4-Difluorobenzoic acid (Cat No.: R023798) is an aromatic carboxylic acid substituted with fluorine atoms at the 3 and 4 positions of the benzene ring. The presence of electron-withdrawing fluorine groups enhances its chemical stability and modulates its acidity and reactivity, making it a valuable intermediate in pharmaceutical, agrochemical, and material science applications. It is commonly used in the synthesis of fluorinated compounds, including active pharmaceutical ingredients and fine chemicals, where fluorination improves metabolic resistance and bioactivity profiles of target molecules.
