| | Uses | 2-Amino-4-nitrobenzoic acid (also known as 4-Nitroanthranilic acid) is primarily used as an intermediate in the synthesis of dyes and pharmaceuticals. It is also used in crystal or eutectic molecular structure research. | | Uses | peptide synthesis | | Definition | ChEBI: 4-nitroanthranilic acid is an aminobenzoic acid that is anthranilic acid with a nitro substituent at position 4. It has a role as a mutagen. It is an aminobenzoic acid and a nitrobenzoic acid. It is functionally related to an anthranilic acid. | | General Description | Orange prisms or orange powder. Sweet taste. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 4-Nitroanthranilic acid is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents. | | Fire Hazard | Flash point data for 4-Nitroanthranilic acid are not available; however, 4-Nitroanthranilic acid is probably combustible. | | reaction suitability | reaction type: solution phase peptide synthesis | | Purification Methods | Crystallise the acid from water, EtOH (m 271o) or aqueous EtOH (m 269o). The acetyl derivative has m 217o (from EtOH), m 222o (from aqueous EtOH). [Chapman & Stephen J Chem Soc 1796 1925, Beilstein 14 II 234, 14 III 975, 14 IV 1087.] |
