LabChem® Diphenylamine, ACS, 100G

LabChem® DIPHENYLAMINE, ACS is solid diphenylamine meeting ACS reagent-grade specifications, a redox indicator that turns deep blue-violet in the presence of oxidizing agents such as dichromate or nitrate in strongly acidic solution. It is manufactured to a high, consistent purity suited to preparing precise indicator solutions. Its distinctive color response makes it valuable in both titrimetric and qualitative testing.

It is commonly used to prepare diphenylamine indicator solutions for dichromate redox titrations, such as the Walkley-Black method for soil organic carbon, and for nitrate spot testing. Its high, consistent purity supports reliable, reproducible results. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
