Verwenden
D-(-)-PANTOLACTONE is an important intermediate in the synthesis of pantothenic acid as well as a degradation product of pantothneic acid in the liver. Causes disorientation and hypothermia, and prevents phenamine-induced hyperthermia.
läuterung methode
Recrystallise the lactone from Et2O/pet ether, diisopropyl ether or *C6H6/pet ether and sublime it at 25o/0.0001mm. It hydrolyses readily to the hydroxy-acid and racemises when heated above 145o. The Brucine salt has m 211-212o (from EtOH). [Kuhn & Wieland Chem Ber 73 1134 1940, and Stiller et al. J Am Chem Soc 62 1779 1940, Bental & Tishler J Am Chem Soc 68 1463 1946, Beilstein 18/1 V 22.]
