Minoxidil (2,4-diamino-6-piperidinopyrimidine 3-oxide) was primarily recognized as a drug for reducing vascular resistance to blood flow. It was later introduced as a more important medicine for topical stimulation of hair growth and baldness reverting as well as treatment of androgenic alopecia through increasing prostaglandin endoperoxide synthesis. In this study, magnetic nanoparticles (MNPs) of spinel ferrites (MFe2 O4, M = Co, Ni, Fe, Cu, and Zn) via solid-state grinding procedure were prepared and then characterized using X-ray diffraction, SEM, transmission electron microscopy, vibrating sample magnetometer, and Fourier transform IR techniques. The prepared nanoferrites were utilized as efficient and green heterogeneous catalysts for N -oxidation of 2,6-diamino-4-chloro-pyrimidine with H2 O2 in refluxing ethanol giving 2,6-diamino-4-chloro-pyrimidine N -oxide as a starting material for the synthesis of 2,4-diamino-6-piperidinopyrimidine 3-oxide (minoxidil). Among the examined nanoferrites, CoFe2 O4 MNPs exhibited prominent catalytic activity giving the product in 95% yield within 60 min. Moreover, the reusability of nano-CoFe2 O4 was examined for 6 consecutive cycles without significant loss of catalytic activity and magnetic property. This study involved multiple reactions and reactants, such as 2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4Related Products of 35139-67-4).
2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4) belongs to pyrimidine derivatives. The aromatic compound pyrimidine, and its derivatives, are ubiquitous in nature. They are found in nucleic acids, vitamins, amino acids, antibiotics, alkaloids, and a variety of toxins. We all know its importance to life – pyrimidine and purine bases are included in the structure of DNA and RNA.Related Products of 35139-67-4
