1.What is diphenylamine ?
Diphenylamine is also known as Diphenylamine redox, with its CAS No. 122-39-4, and it has the molecular formula of C12H11N and a molecular weight of 169.22. The other properties of diphenylamine include: Density: 1.16; Melting point: 52-54 ºC; Boiling point: 302 ºC; Flash point : 152 ºC; Water solubility: Slightly soluble. 0.03 g/100 mL. Diphenylamine is often used for producing stabilizer of explosive and fuel.
2. Diphenylamine test
One of the suppliers of diphenylamine, Hangzhou Chemfar Ltd., which has more than 20 years' experience focused on providing integrated development and manufacturing service to the pharmaceutical and fine chemical industry, showed that diphenylamine was of great importance in many experiments.
For example, in the identification of DNA, DNA can be identified chemically with the dische diphenylamine test. One major difference between DNA and RNA is their sugar: DNA contains deoxyribose, whereas RNA contains ribose. This is what is diphenylamine test for deoxyribose for. In this process, the reaction between the Dische reagent and 2-deoxypentose results in the development of a blue color. The reaction depends on the conversion of the pentose to w-hydroxylaevulinic aldehyde which then reacts with diphenylamine to give a a blue colored complex. The intensity of the blue color is proportional to the concentration of DNA. Dische reagent does not react with the ribose sugar in RNA and does not form a blue-colored complex. Dische diphenylamine test -- A chemical test utilized to detect the presence of DNA in a substance.
