N-ethyl-6-methoxyquinazolin-4-amine CAS 929504-75-6

Description

Compared with other compounds in its class, the molecular weight of 203.24 g/mol gives N-ethyl-6-methoxyquinazolin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-ethyl-6-methoxyquinazolin-4-amine (CAS 929504-75-6), molecular formula C11H13N3O and molecular weight 203.24 g/mol, is a CATO reference standard with documented purity and traceability.

N-ethyl-6-methoxyquinazolin-4-amine (C11H13N3O) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), N-ethyl-6-methoxyquinazolin-4-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
