Description
Diaminopyrimidine Oxide (CAS 74638-76-9, EC 616-121-2, formula C4H6N4O) is a pyrimidine-derived compound commercially known under trade names including Kopexil, Aminexil, and Mexoryl SAG. It is also referenced in pharmaceutical contexts as Minoxidil Impurity 8, reflecting its structural relationship to minoxidil.
In personal care formulations, Diaminopyrimidine Oxide is used primarily in scalp treatment products targeting hair loss. It functions by inhibiting the perifollicular fibrosis mechanism, helping to maintain follicle flexibility and prolong the active growth phase of hair. It is also applied as a surface-modifying agent to improve wetting behaviour on biological substrates.
This material is supplied to REACH-compliant standards for the European market and is relevant to both cosmetic and pharmaceutical intermediate applications. Procurement teams should confirm applicable cosmetic regulation compliance under EU Regulation 1223/2009. Contact our team for available grades, lot documentation, and packaging options.
