HPLC Method for Diphenylamine on Newcrom R1 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Diphenylamine
Diphenylamine is an organic compound with the chemical formula (C6H5)2NH. It is used primarily to distinguish DNA from RNA with the Dsiche test, as a scald inhibitor in apples, antioxidant, stabilizer of smokeless powder, and a redox indicator. It’s a derivative of aniline, while Metanil Yellow, Disperse Orange 1, and Acid Orange 5 are derivatives of Diphenylamine.
