Verwenden
o-Toluic acid is part of a group of Benzoic acid (B203900) derivatives that possess inhibitory activity against mushroom tyrosinases. o-Toluic acid is also used as a reagent to synthesize halogen-substituted benzoic acids (such as 2,4-Dichlorobenzoic acid [D431955]), which have potential muscle stimulating effects.
Definition
ChEBI: A methylbenzoic acid that is benzoic acid substituted by a methyl group at position 2.
Air & Water Reaktionen
Fine dust dispensed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. . Insoluble in water.
Brandgefahr
Flash point data for o-Toluic acid are not available. o-Toluic acid is probably combustible. Fine dust dispensed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard.
läuterung methode
Crystallise the acid from *benzene (2.5mL/g) and dry in air. The S-benzylisothiuronium salt has m 146o (from aqueous EtOH). [Beilstein 9 IV 1697.]
