The occurrence of (R)-3-(2,3-dihydroxypropyl)-6-fluoro-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione 1035555-63-5 C17H16FIN4O4 X7440 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-3-(2,3-dihydroxypropyl)-6-fluoro-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione 1035555-63-5 C17H16FIN4O4 X7440 (CAS 1035555-63-5), molecular formula C17H15F2IN4O4 and molecular weight 504.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (R)-3-(2,3-dihydroxypropyl)-6-fluoro-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione 1035555-63-5 C17H16FIN4O4 X7440 (C17H15F2IN4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 504.23 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
