6-(4-Fluorophenyl)-4-imino-3-phenyl-1,3,4,7-tetrahydropyrimido[5,4-d]pyrimidine-2,8-dione CAS 1119391-90-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-(4-Fluorophenyl)-4-imino-3-phenyl-1,3,4,7-tetrahydropyrimido[5,4-d]pyrimidine-2,8-dione.

6-(4-Fluorophenyl)-4-imino-3-phenyl-1,3,4,7-tetrahydropyrimido[5,4-d]pyrimidine-2,8-dione (CAS 1119391-90-0), molecular formula C18H12FN5O2 and molecular weight 349.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 6-(4-Fluorophenyl)-4-imino-3-phenyl-1,3,4,7-tetrahydropyrimido[5,4-d]pyrimidine-2,8-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
