Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((1,4-Dioxan-2-yl)methoxy)-9-(pyridin-2-ylmethoxy)-6,7-dihydro-4H-pyrimido[6,1-a]isoquinolin-4-one.
2-((1,4-Dioxan-2-yl)methoxy)-9-(pyridin-2-ylmethoxy)-6,7-dihydro-4H-pyrimido[6,1-a]isoquinolin-4-one (CAS 1445846-30-9) is a high-purity analytical reference standard with the molecular formula C23H23N3O5 and a molecular weight of 421.45 g/mol.
2-((1,4-Dioxan-2-yl)methoxy)-9-(pyridin-2-ylmethoxy)-6,7-dihydro-4H-pyrimido[6,1-a]isoquinolin-4-one (C23H23N3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
