Chemical Structure
Description
3-Methyl-6-(methylamino)-1-propylpyrimidine-2,4(1H,3H)-dione (CAS 66400-20-2), molecular formula C9H15N3O2 and molecular weight 197.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Methyl-6-(methylamino)-1-propylpyrimidine-2,4(1H,3H)-dione (C9H15N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 3-Methyl-6-(methylamino)-1-propylpyrimidine-2,4(1H,3H)-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
