4-Aminobenzoic Acid (PABA)

The 4-Aminobenzoic Acid (PABA) by Dinâmica, available at LojaLab, is a bifunctional aromatic compound bearing an amino group and a carboxylic-acid group in para positions on the benzene ring. This structural arrangement allows the reagent to undergo transformations typical of aromatic amines, including diazotization, coupling and imine formation, as well as reactions involving the carboxylic-acid group, such as esterification and amide formation. It is therefore used as an intermediate in organic synthesis, dye chemistry, polymeric materials and the preparation of functionalized derivatives. In biochemical and microbiological research, PABA may also be used as an experimental compound associated with bacterial folate biosynthesis when concentration and test conditions are defined by the protocol.
