Chemical Structure
Description
The occurrence of 7-Methoxypyrido[3,2-d]pyrimidin-4(3H)-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-Methoxypyrido[3,2-d]pyrimidin-4(3H)-one (CAS 1600511-85-0), molecular formula C8H7N3O2 and molecular weight 177.16 g/mol, is a CATO reference standard with documented purity and traceability.
7-Methoxypyrido[3,2-d]pyrimidin-4(3H)-one (C8H7N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
