1.Reference Material For PTA Quality Control: p-Toluic acid is one of the impurities controlled in purified terephthalic acid, and the PTA industrial test method standard covers determination of 4-CBA and p-toluic acid, so laboratories and PTA producers use it as a reference material.
2. Synthesis Intermediate For PAMBA And p-Toluonitrile: It is used as an intermediate in the synthesis of p-aminomethylbenzoic acid (PAMBA) and p-toluonitrile and related substituted benzoic acid derivatives.
3. Intermediate For Polymer Stabilisers: It is also used as an intermediate for polymer stabilisers and light sensitive compounds, where a para-substituted benzoic acid scaffold is required.
