Collection: Purine Alkaloids
Purine Alkaloids — includes hydroxylated and methylated purine derivatives such as xanthines, uric acid, and theophylline derivatives that are structurally related to natural purine nucleobases. This group is widely studied in heterocyclic chemistry and purine metabolism biochemistry.
Compounds in this category are used as analytical standards and starting materials for synthesis in purine metabolism research, including the pathways of uric acid formation and degradation in biochemical models. Derivatives such as 8-bromotheophylline and aminophylline are also used as synthesis intermediates to modify the purine core structure in structure-activity relationship studies, while theophylol is used as a test material in xanthine derivative research.
Example products in this collection: TCI X0004 69-89-6 Xanthine, TCI C0293 85-18-7 8-Chlorotheophylline, TCI T3646 5415-44-1 1,3,7-Trimethyluric Acid, TCI C1103 74409-52-2 1-(3-Chloropropyl)theobromine, TCI T2941 652-37-9 Theophylline-7-acetic Acid, TCI C2042 58-08-2 Caffeine, TCI B3456 10381-75-6 8-Bromotheophylline, TCI D3600 479-18-5 7-(2,3-Dihydroxypropyl)theophylline.
Pay attention to the degree of methylation and the position of substituents on the purine ring, the crystal or hydrate form, and the analytical purity required for reference standard applications. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
