Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Methylfuro[2,3-d]pyrimidin-4(3H)-one (CAS 1283372-48-4), a certified reference material (molecular formula C7H6N2O2, MW 150.13 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H6N2O2, 5-Methylfuro[2,3-d]pyrimidin-4(3H)-one contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 150.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
