141635-93-0 4,6,7,8-Tetrahydro-8-hydroxy-6-methylpyrimido[1,2-a]purin-10(3H)-one (Mixture of Diastereomers) 5,6,7,8-Tetrahydro-4-hydroxy-6-methylpyrimido[1,2-a]purin-10(1H)-one (CAS 141635-93-0) is a high-purity analytical reference standard with the molecular formula C9H11N5O2 and a molecular weight of 221.22 g/mol.
Structurally, 141635-93-0 4,6,7,8-Tetrahydro-8-hydroxy-6-methylpyrimido[1,2-a]purin-10(3H)-one (Mixture of Diastereomers) 5,6,7,8-Tetrahydro-4-hydroxy-6-methylpyrimido[1,2-a]purin-10(1H)-one (C9H11N5O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 221.22 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
