Chemical Structure
Description
1-methyl-2-pentyl-2H-pyrazino[2,1-b]quinazoline-3,6(1H,4H)-dione (CAS 866010-14-2) is a high-purity analytical reference standard with the molecular formula C17H21N3O2 and a molecular weight of 299.37 g/mol.
The molecular framework of 1-methyl-2-pentyl-2H-pyrazino[2,1-b]quinazoline-3,6(1H,4H)-dione (C17H21N3O2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
