Anthranilic acid

[10] Above 81 °C (178 °F; 354 K), it converts to an orthorhombic form with space group Pbca, which is not triboluminescent; a non-triboluminescent monoclinic phase with similar structure is also known.[10] In 1840-1841, Carl Julius Fritzsche was able to extract and crystallize two acids from the products of reaction of indigo dye with caustic potash, which he called chrysanilic and anthranilic acids after their colors before purification (golden yellow and black respectively) and the plant anil (Indigofera suffruticosa).This cation can be used to generate benzyne,[20] dimerized to give diphenic acid,[21] or undergo diazonium coupling reactions such as in the synthesis of methyl red.[23] Chlorination of anthranilic acid gives the 2,4-dichloro derivative, which can undergo reductive coupling to form a biaryl compound.[24] It is also a DEA List I Chemical because of its use in making the now-widely outlawed euphoric sedative drug methaqualone (Quaalude, Mandrax).

NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oil Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
Anthranilate is the biosynthetic precursor to the amino acid tryptophan.
