2-Amino-7,8-dihydro-7,7-dimethyl-4-propyl-5(6H)-quinazolinone CAS 331966-05-3 chemical structure

Description

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.

2-Amino-7,8-dihydro-7,7-dimethyl-4-propyl-5(6H)-quinazolinone (CAS 331966-05-3) is a high-purity analytical reference standard with the molecular formula C13H19N3O and a molecular weight of 233.31 g/mol.

2-Amino-7,8-dihydro-7,7-dimethyl-4-propyl-5(6H)-quinazolinone (C13H19N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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.
