Chemical Structure
Description
The occurrence of 5-Amino-6-methyl-3-phenylpyrimidin-4(3H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Amino-6-methyl-3-phenylpyrimidin-4(3H)-one (CAS 65765-92-6), a certified reference material (molecular formula C11H11N3O, MW 201.22 g/mol) for analytical method development and quality control.
5-Amino-6-methyl-3-phenylpyrimidin-4(3H)-one (C11H11N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
