147-85-3 Usage

Purification Methods

A likely impurity is hydroxyproline. Purify L-proline via its picrate which is crystallised twice from water, then decomposed with 40% H2SO4. The picric acid is extracted with diethyl ether, the H2SO4 in solution is precipitated with Ba(OH)2, and the filtrate is evaporated. The residue is crystallised from hot absolute EtOH [Mellan & Hoover J Am Chem Soc 73 3879 1951] or EtOH/Et2O. Its solubility in H2O is >100%. It sublimes at 182-187o/0.3mm with 99.4% recovery and unracemised [Gross & Gradsky J Am Chem Soc 77 1678 1955]. It is hygroscopic and is stored in a desiccator. [Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 pp 2178-2199 1961, Beilstein 22 III/IV 8, 22/1 V 31.]
