6-Amino-1,3-dimethyl-5-nitrosouracil

It serves as a precursor in the Traube purine synthesis route, mainly because the 5-nitroso group provides the necessary nitrogen functionality for the imidazole ring closure required to form the purine nucleus of theophylline. 6-Amino-1,3-dimethyl-5-nitrosouracil (often abbreviated as 5-nitroso-6-amino-1,3-dimethyluracil or ANDMU) is a critical intermediate in the commercial and laboratory synthesis of theophylline.
