| BETAINE MONOHYDRATE Usage And Synthesis |
| Purification Methods |
Crystallise betaine from aqueous EtOH or EtOH/Et2O. The monohydrate loses H2O above 100o. Betaine undergoes internal alkylation to methyl dimethylaminoacetate Purification of Biochemicals — Amino Acids and Peptides above its melting point. It is also prepared by treating the hydrochloride (below) with silver oxide and recrystallising from EtOH/Et2O.
