Two forms of crystals are observed for 3-methylbuphedrone when mixed with aqueous gold chloride reagent. The substance, dissolved in water, 10% hydrochloric acid, or 10% acetic acid, gives yellow rectangular tablets when grown slowly at lower concentrations. The tablets when grown quickly may grow smaller and longer to appear as blades stacked on each other. Both forms appear very bright under crossed polars. The thick tablets do not give good IR spectra.
