Product Name:2-Methylthio-4,6-dihydroxypyrimidine
English Name:2-Methylthio-4,6-dihydroxypyrimidine
CAS No.:1979-98-2
Aliases:4,6-Dihydroxy-2-(methylthio)pyrimidine, 2-(Methylthio)pyrimidine-4,6-diol, 2-Methylthio-4,6-pyrimidinedione, 2-Methylsulfanylpyrimidine-4,6-diol
Molecular Formula:C5H6N2O2S
Physical Properties:Off-white to pale yellow crystalline powder, odorless or with a slight characteristic odor. Melting point approximately 285 °C (decomposes). Slightly soluble in water; soluble in methanol, ethanol, acetone and other organic solvents; soluble in alkaline aqueous solutions. Exhibits tautomerism between 4,6-dihydroxy and 4,6-dione forms, with interconversion occurring under acidic or basic conditions.
Uses:This product is an important organic synthesis intermediate, mainly used in the pharmaceutical industry for the preparation of pyrimidine-containing drugs, serving as a key intermediate for antiviral and antitumor agents. It is also used in the synthesis of pyrimidine-based agrochemicals such as herbicides and fungicides. Through functionalization of the pyrimidine ring, various fine chemical derivatives can be prepared.
Technical Specifications:
Appearance: off-white to pale yellow crystalline powder
Assay (HPLC) ≥ 98.0%
Melting point: approximately 285 °C (decomposes)
Loss on drying ≤ 0.5%
Residue on ignition ≤ 0.2%
