5% Aqueous HAuCl4
25B-NBOMe dissolved in water, 10% hydrochloric acid or 10% acetic acid forms yellow dendrites with comb like arms. The shape of the crystal is better observed under acidic conditions where the formations are larger with distinct features of the combs.
5% HAuCl4 in 1:2 concentrated H2SO4: H2O
Colorless, light floral dendrites of 25NBOMe are formed with the acidic gold chloride reagent. The crystals are formed like a floating skin at the edge of the drop and can be best visualized under crossed polars.
Platinic Chloride (H2PtCl6)
Clusters and rosettes of colorless, irregular plates are observed for 25B-NBOMe with platinic chloride reagent. The crystals habit is tighter and more similar to a rosette with 25B-NBOMe dissolved in water. The crystal size is also larger in water. In acidic solutions, the crystal habit is similar to loose clusters of light colorless plates and blades. Some individual crystals are also observed.
