The use of 2C-E as a psychedelic drug is well established and cases of mistaken identity appear rare but we noticed that there were no reagent test results for it using the froehde reagent online.
2C-E reacts with the froehde reagent to give a bright lime green colour within a few seconds. You can see the image below
Also shown is the reaction of 2C-E with the marquis reagent. The colour is an orange-brown after twenty seconds.
