Product Overview: 4,6-Dihydroxy-2-methylpyrimidine (CAS 40497-30-1 / 1194-22-5)
4,6-Dihydroxy-2-methylpyrimidine, listed under both CAS 40497-30-1 and CAS 1194-22-5, is a pyrimidine-based organic compound with the molecular formula C₅H₆N₂O₂ and a molecular weight of 126.11 g/mol. The molecule carries two hydroxyl groups at the 4 and 6 positions and a methyl group at position 2, giving it a rigid heterocyclic core that supports selective functionalization in downstream synthesis.
In practice, this pyrimidine building block is used as a precursor for substituted pyrimidine derivatives, particularly in agrochemical synthesis and fine chemical production. Its dihydroxy structure allows alkylation, acylation, and condensation reactions at the 4 and 6 positions, making it a versatile starting material for heterocyclic chemistry.
Alfa Chemical supplies this product from our facility in Zhengzhou, China at ≥99% purity, with appearance controlled to a white solid and melting point above 300°C. Each batch is tested in-house by HPLC, and a batch-specific COA and SDS ship with every order. Packaging is available in 25kg drums, with custom options on request.
