3,4-Dinitrobenzoic acid is a nitrobenzoic acid that has a hydrogen bond. 3,4-Dinitrobenzoic acid is activated by the loss of a proton and it reacts with amines to form diazonium salts. It can be found in plants and animals as an intermediate in the metabolism of tyrosine and tryptophan. 3,4-Dinitrobenzoic acid is used in analytical chemistry to detect the presence of amines. The functional groups on 3,4-dinitrobenzoic acid are carboxylic acid and nitro. Ribulose is an example of a molecule containing these functional groups.

Methyl 4-aminobenzoate is a chemical compound that is used as a fluorescence probe in the study of DNA replication. It can be used to detect the presence of viral RNA in cell culture, and has been shown to inhibit the replication of bacterial RNA. Methyl 4-aminobenzoate binds to guanine residues in DNA and forms an alkyl bond with them. This prevents the binding of other amino acids, which are essential for DNA replication. Methyl 4-aminobenzoate has also been shown to have pharmacokinetic properties that make it useful for intravenous administration and oral administration.

3-N-Maleimidobenzoic acid is a chemical crosslinking agent that reacts with proteins through the formation of an amide bond. It has been shown to react with both actin subunits and human immunoglobulin. This molecule also reacts with spermatozoa, which are composed primarily of actin filaments, and is used in the preparation of polyclonal antibodies. 3-N-Maleimidobenzoic acid can be used to fix antigen onto a solid support for immunological purposes. It is also a cross-linking agent that can be used in cytochalasin B experiments to inhibit plastid activity in chloroplasts. 3-N-Maleimidobenzoic acid reacts with monoclonal antibodies by forming an amide bond, which can be used as a reaction product.

2-Bromo-6-fluorobenzonitrile is an organic compound with a molecular formula of C6H3BrF. It is a colorless liquid that is used as a precursor in the synthesis of other compounds. 2-Bromo-6-fluorobenzonitrile has been shown to be an efficient fluorophore and can be activated by electron transfer, thermally, or chemically. 2-Bromo-6-fluorobenzonitrile also has a quantum efficiency of 0.5% and transport properties that make it ideal for fluorescence microscopy.
