일반 설명

7-Methylxanthine is an oxopurine, which belongs to the class of xanthines. It may be synthesized by the reaction between 4-amino-1-methylimidazole-5-carboxamide and diethyl carbonate.

애플리케이션

7-Methylxanthine can be used as a building block to synthesize tricyclic imidazo[2,1-i]purinone derivatives as potential adenosine receptor antagonists.

HPLC Analysis of Xanthines on Purospher® STAR RP-18 endcapped

Xanthine is a purine base found in most human body tissues and fluids as well as in other organisms. Methylated xanthines (methylxanthines), which include caffeine, paraxanthine, theobromine, and theophylline, commonly used for their effects as mild stiµlants and as bronchodilators, notably in the treatment of asthma symptoms. This application shows the efficient separation of several common xanthines and may be applied their analysis in any number of desired matrices.
