Chemical Structure
Description
1031605-64-7 7-(4-Chlorophenyl)-1-ethylpyrimido[4,5-d]pyrimidine-2,4(1H,3H)-dione MFCD14716310 (CAS 1031605-64-7) is a high-purity analytical reference standard with the molecular formula C14H11ClN4O2 and a molecular weight of 302.72 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1031605-64-7 7-(4-Chlorophenyl)-1-ethylpyrimido[4,5-d]pyrimidine-2,4(1H,3H)-dione MFCD14716310 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.72 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.
