   en.wikipedia.org/wiki/2,4-Diaminotoluene

   It is mainly used to manufacture toluene diisocyanate, which is a key raw material in polyurethane chemistry. [4] It is still the starting material used when non-phosgene methods of production of toluene diisocyanate are used. [5] [6] It is also a degradation product of polyurethane materials produced using toluene diisocyanate.

5. 2,5-Diaminotoluene - Wikipedia

   en.wikipedia.org/wiki/2,5-Diaminotoluene

   2,5-Diaminotoluene is prepared through electrolytic reduction of 2,5-dinitrotoluene. [3] Other methods include the reductive cleavage of 4-amino-2,3'-dimethylazobenzene as well as the condensation of 2-amino-1-methylbenzene and toluene-4-sulphonyl chloride to produce 4-toluenesulphono-2-toluidide which is then coupled with diazotized aminobenzenesulphonic acid and reduced.

9. Oxalic acid - Wikipedia

   en.wikipedia.org/wiki/Oxalic_acid

   Oxalic acid is an important reagent in lanthanide chemistry. Hydrated lanthanide oxalates form readily in very strongly acidic solutions as a densely crystalline, easily filtered form, largely free of contamination by nonlanthanide elements: 2 Ln 3+ + 3 H 2 C 2 O 4 → Ln 2 (C 2 O 4) 3 + 6 H +
