Formaldehyde reacts with tryptophan in the presence of sulfuric acid and iron, nickel, or cobalt and gives a violet color with absorption maximum at 575 nm. Nanomoles of formaldehyde can be estimated spectrophotometrically by using this reaction which is also very specific. Other aminoacids. sugars
