Applications

It is applied in organic synthesis. 5-Nitro-o-toluidine finds application as an intermediate in the synthesis of Pigment Red 17 (C.I. 12 390) and Pigment Red 22 (C.I. 12 315). It is also employed in conjunction with certain C.I. coupling components. It also serves as a precursor for a wide assortment of azo dyes of various red, yellow, orange, violet, and brown hues. It can also be employed as analytical standard for the surfactant mediated transformations (-254nm) of 2,4-dinitrotoluene.

Notes

C.I. 37105. Sensitive to moisture and light. Store away from oxidizing agents and bases. Keep the container tightly closed in a cool, dry place.
