Chemical Structure

3-Cyclopentyl-7-((1-(furan-2-yl)ethyl)amino)pyrimido[4,5-d]pyrimidine-2,4(1H,3H)-dione CAS 1396857-35-4 chemical structure

Description

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.

3-Cyclopentyl-7-((1-(furan-2-yl)ethyl)amino)pyrimido[4,5-d]pyrimidine-2,4(1H,3H)-dione (CAS 1396857-35-4) is a high-purity analytical reference standard with the molecular formula C17H19N5O3 and a molecular weight of 341.36 g/mol.

The molecular framework of 3-Cyclopentyl-7-((1-(furan-2-yl)ethyl)amino)pyrimido[4,5-d]pyrimidine-2,4(1H,3H)-dione (C17H19N5O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
