6-Amino-5-formamido-1,3-dimethyluracil

It is typically synthesized from 5,6-diamino-1,3-dimethyluracil, and upon heating, it cyclizes to produce theophylline. 6-Amino-5-formamido-1,3-dimethyluracil is a key intermediate in the synthesis of theophylline (a bronchodilator), used as a direct precursor that undergoes cyclization to form the final purine ring structure.
