D-펜토락톤 C화학적 특성, 용도, 생산
화학적 성질
WHITE CRYSTALLINE POWDER OR CRYSTALS용도
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.일반 설명
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.Purification Methods
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.
