The carbonyl group typically reacts with the electron rich 2-position of the indole but may also react at the C-3 or N-1 positions. Not all indole alkaloids give a colored adduct as result of steric hindrance which does not allow the reaction to proceed. If a urine sample is left to oxidize in air to form urobilin the reagent will not detect the urobilinogen. By adding few drops of reagent to 3 mL of urine in a test tube one can see a change of color, to dark pink or red. The degree of color change is proportional to the amount of urobilinogen in the urine sample. Isaac Asimov , in a humorous essay entitled 'You, too, can speak Gaelic', \\\\\\\\\\\\\[4\\\\\\\\\\\\\] reprinted in the anthology Adding a Dimension among others, traces the etymology of each component of the chemical name 'para-di-methyl-amino-benz-alde-hyde' e. Asimov points out that the name can be pronounced to the tune of the familiar jig ' The Irish Washerwoman ', and relates an anecdote in which a receptionist of Irish descent, hearing him singing the syllables thus, mistook them for the original Gaelic words to the jig.
