8-Chlorotheophylline Chemical Properties, Uses, Production
Chemical Properties
white to light yellow crystal powder
Uses
8-Chlorotheophylline is a stimulant drug. It can be used as a binding agent to form stable salts of pharmaceutical drugs.
Definition
ChEBI: 1,3-Dimethylxanthine in which the hydrogen at position 8 is substituted by chlorine.
Purification Methods
It crystallises from H2O or EtOH (m 304o, dec). The choline salt crystallises from H2O with m 60-62o (2 H2O) and m 97-99o (anhydrous). [Beilstein 26 H 473, II 276, 26 III/IV 2442.]
