What is ehrlich reagent?

Ehrlich reagent is a chemical solution used for the detection of certain substances, particularly drugs such as LSD and other indole alkaloids. It is a mixture of para-dimethylaminobenzaldehyde and concentrated sulfuric acid.

When Ehrlich reagent is added to a sample containing indole alkaloids, a color change reaction occurs. The reagent turns a bluish-purple color in the presence of these substances, allowing for their identification and detection.

However, it is important to note that Ehrlich reagent is only a presumptive test and cannot definitively confirm the presence of a specific substance. Additional testing may be required for confirmation.

Due to the potential health risks associated with handling sulfuric acid, Ehrlich reagent should be used with caution and proper safety measures should be taken.
