Pyrrolidinyl diaminopyrimidine oxide

Pyrrolidinyl diaminopyrimidine oxide (CAS 55921-65-8, EC 611-333-1), also known by the trade names Nanoxidil and Triaminodil, is a synthetic pyrimidine derivative with the molecular formula C8H13N5O. It carries no assigned E-code and is classified within pharmaceutical intermediates.

In personal care formulations, it is used as an active ingredient in topical scalp treatments where it functions as a potassium channel opener, promoting follicular activity at the dermal level. It also serves as a pH-regulating agent in cosmetic systems, where its buffering capacity helps stabilise formulation pH within target ranges for dermal compatibility.
