2-Methyl-5-nitroaniline, 98+%

Description

CAS: 99-55-8 | C7H8N2O2 | 152.15 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
