((3aR,4R,6R,6aR)-6-(4-Chloro-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-2,2,3a-trimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl)methanol (CAS 2278357-65-4) is a high-purity analytical reference standard with the molecular formula C15H18ClN3O4 and a molecular weight of 339.77 g/mol.
Based on its molecular formula C15H18ClN3O4, ((3aR,4R,6R,6aR)-6-(4-Chloro-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-2,2,3a-trimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl)methanol contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 339.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
