Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 149.13 g/mol gives 6-Fluoropyrido[3,4-d]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Fluoropyrido[3,4-d]pyrimidine (CAS 2089309-98-6), molecular formula C7H4FN3 and molecular weight 149.13 g/mol, is a CATO reference standard with documented purity and traceability.
6-Fluoropyrido[3,4-d]pyrimidine (C7H4FN3) contains a nitrile group, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
