2-(4-(6,7-Dihydro-5h-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)ethan-1-ol (CAS 1375166-39-4) is a high-purity analytical reference standard with the molecular formula C13H20N4O and a molecular weight of 248.32 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-(4-(6,7-Dihydro-5h-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)ethan-1-ol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 248.32 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).
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.
