The Ehrlich Reagent is the most widely used kit to detect compounds with an indolic ring in their chemical structure.
The reagent is prepared by dissolving 0.5–2.0 g of p–dimethylaminobenzaldehyde (DMAB) in 50 mL of 95% ethanol and 50 mL of concentrated hydrochloric acid and is best used when fresh. Other alcohols, such as 1-propanol, can also be used as well.
OUR KIT INCLUDES
- One 5ml Bottle Containing The Ehrlich Reagent
- FREE Safety Gloves
- One Test Tube
- Detailed Instructions
- Color Chart For Reading Results
- Fresh Batches Made Every Week For Optimal Quality
- FREE Shipping To All Of Europe
Place a small sample (2-5mg) of the substance you want to analyze in the provided plastic tube. If preferred, the test can be performed on a white ceramic surface for clearer results (e.g. kitchen plate). Add a drop of Smplest Ehrlich to the sample and expect it to change colors.
The ehrlich test confirms the presence of indole groups in a sample. We highly recommend testing your sample with the Hofmann reagent as well. This will also serve as a reliable validation of the results obtained with the Ehrlich reagent.
Upon reaction, the sample will gradually turn purple/magenta. The reaction can take a while to take place (up to 3 minutes), especially if the substance is impregnated in blotter paper.
When finished, clean all material thoroughly with plenty of water. The entire protocol takes approximately 5 minutes. Store at cold temperature, preferably in the freezer for longer shelf life (up to 12 months).
