Crystallization of Supersaturated Sodium Acetate  
A supersaturated solution of sodium acetate is poured onto one small sodium acetate crystal. Crystals form from the liquid immediately upon contact with the seed crystal. A thermometer shows that the crystallization process is exothermic. A chemical hot pack is shown as an example of a commercially available supersaturated solution.

Synthesis of Albendazole Metabolite: Characterization and HPLC Determination  Graciela Mahler, Danilo Davyt, Sandra Gordon, Marcelo Incerti, Ivana Núñez, Horacio Pezaroglo, Laura Scarone, Gloria Serra, Mauricio Silvera, and Eduardo Manta
In this laboratory activity, students are introduced to the synthesis of an albendazole metabolite obtained by a sulfide oxidation reaction. Albendazole as well as its metabolite, albendazole sulfoxide, are used as anthelmintic drugs. The oxidation reagent is H2O2 in acetic acid. The reaction is environmental friendly, fast, and proceeds with high yield. The crude reaction is analyzed by HPLC chromatography to determine purity. The simplicity of the experiment allows students to study chiral concepts, physicochemical and spectroscopic properties of the compounds, and HPLC determinations.

Synthesis of Quaternary Ammonium Salts of Tricyclic Cationic Drugs: A One-Pot Synthesis for the Bioorganic Chemistry Laboratory  Linda S. Brunauer, Abid C. Mogannam, Won B. Hwee, and James Y. Chen
Describes a one-pot conversion of tricyclic cationic drugs to their quaternary ammonium forms for a widely used bioactive drug, chlorpromazine, a phenothiazine-based antipsychotic. The conversion of parent drug to the methylated form was evaluated by qualitatively measuring its ability to induce alterations in the shape of mammalian erythrocytes.
