6-hydroxymethyl-7,8-dihydropterin diphosphate (6-hydroxymethyl-dihydropterin diphosphate) is the pterin precursor for the biosynthesis of several important cofactors, including tetrahydropteroyl mono-L-glutamate, methanopterin and sarcinapterin. The compound is always synthesized from GTP, but the enzymes involve may differ among organisms.

This pathway, which is found in bacteria, fungi and plants, starts with GTP cyclohydrolase I, an enzyme that converts GTP into 7,8-dihydroneopterin 3'-triphosphate. The triphosphate motif is removed in a process that is still not completely understood, and the resulting 7,8-dihydroneopterin is converted to 6-hydroxymethyl-7,8-dihydropterin by dihydroneopterin aldolase (FolB).

In plants the pterin moiety is formed from GTP in the cytosol.
