When does a spray of diphenylamine reagent on TLC gives blue coloration?
Diphenylamine is a reagent for DNA.
Diphenylamine will turn blue in the presence of?
nitrites.
Is diphenylamine organic or inorganic?
Diphenylamine is an organic compound. It is a derivative of aniline and is commonly used as an antioxidant in various industries, including the production of rubber, plastics, and explosives.
What will diphenylamine turn blue in the prescense of?
Diphenylamine turns blue in the presence of nitrates. This reaction is commonly used in the Griess test to detect the presence of nitrate ions.
What color changes indicate a positive result for dische diphenylamine?
A positive result for dische diphenylamine test would be indicated by a deep blue color change in the solution. This color change indicates the presence of DNA, as dische diphenylamine reacts with deoxyribose sugars in DNA to produce a blue color.
When does a spray of diphenylamine reagent on TLC gives blue coloration?
Diphenylamine is a reagent for DNA.
Why does blue colour appears in diphenylamine test?
The appearance of a blue color in the diphenylamine test indicates the presence of a reducing sugar, such as a reducing sugar or pentose sugar. The reaction occurs when the sugar present in the sample reduces diphenylamine to form a blue compound.
How to prepare nitrate test solution using diphenylamine in sulphuric acid?
To prepare a nitrate test solution using diphenylamine in sulfuric acid, you can mix diphenylamine with concentrated sulfuric acid in a specific ratio. Typically, a 0.1% diphenylamine solution in concentrated sulfuric acid is used for nitrate testing. Follow safety precautions when working with concentrated sulfuric acid as it is corrosive.

A positive result for dische diphenylamine test would be indicated by a deep blue color change in the solution. This color change indicates the presence of DNA, as dische diphenylamine reacts with deoxyribose sugars in DNA to produce a blue color.
What turns diphenylamine blue?
Diphenylamine turns blue in the presence of oxidizing agents, such as nitrates or nitrites. This color change occurs due to the formation of a blue-colored complex with the oxidizing agent.
What is diphenylamine test for deoxyribose for?
The diphenylamine test is used to detect the presence of deoxyribose sugar in nucleic acids. Deoxyribose reacts with diphenylamine in acidic conditions to produce a blue color, indicating the presence of deoxyribose in the sample. This test is commonly used in biochemistry laboratories to analyze the composition of nucleic acids.
Why does the Diphenylamine test only react with DNA?
The Diphenylamine test is specific to DNA because it reacts with the deoxyribose sugar present in the DNA backbone. The test detects the presence of DNA by forming a blue color complex with the deoxyribose, which is unique to DNA and not found in other nucleic acids like RNA.
What is the use of Diphenylamine reagent?
Diphenylamine reagent is commonly used in analytical chemistry to detect the presence of nitrates and nitrites. It reacts with these compounds to form a blue-colored compound, making it useful for qualitative analysis. Diphenylamine can also be used as an antioxidant in certain products to prevent degradation due to oxidation.
Why diphenylamine is called internal indicator?
Diphenylamine is considered an internal indicator because it changes color in the presence of nitrates by forming a blue complex. This color change is used to detect the presence of nitrates in solutions without the need for an external indicator.
