1,7-Dimethylxanthine (also known as Paraxanthine) is a natural xanthine alkaloid and the primary metabolite of caffeine in humans. Unlike caffeine, it has a shorter half-life and distinct pharmacological profile, making it valuable for research applications.
1,7-Dimethylxanthine is the major metabolite of caffeine, accounting for approximately 80% of caffeine metabolism. It is also found naturally in certain plants.

Q: Is 1,7-Dimethylxanthine the same as Paraxanthine?
A: Yes. Paraxanthine is the common name for 1,7-dimethylxanthine.
Q: What is the difference between 1,7-Dimethylxanthine and Caffeine?
A: Caffeine has three methyl groups (1,3,7-trimethylxanthine). 1,7-Dimethylxanthine has two methyl groups (at positions 1 and 7) and is the primary metabolite of caffeine in humans.
Q: Is 1,7-Dimethylxanthine found naturally?
A: Yes, in small amounts in certain plants, but it is primarily known as a caffeine metabolite.
