Chemical Structure

(4-ethoxyquinazolin-6-yl)methanamine CAS 2227205-46-9 chemical structure

Description

(4-ethoxyquinazolin-6-yl)methanamine (CAS 2227205-46-9), molecular formula C11H23N3O and molecular weight 213.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4-ethoxyquinazolin-6-yl)methanamine (C11H23N3O) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
