Overall recommended test:
2C-B gives characteristic crystals with gold-based reagents and these crystals can also be studied with IR microspectroscopy. The aqueous gold chloride reagent is ideal, among the gold-based reagents, for obtaining reproducible IR spectra because of the availability of large crystals.
