Description

1-(2-Hydroxyethyl)-3-methylquinazoline-2,4(1H,3H)-dione (CAS 113366-93-1) is a high-purity analytical reference standard with the molecular formula C11H12N2O3 and a molecular weight of 220.22 g/mol.

Structurally, 1-(2-Hydroxyethyl)-3-methylquinazoline-2,4(1H,3H)-dione (C11H12N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 220.22 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
