Chemical Structure

2-Methylquinazolin-4-amine CAS 3440-46-8 chemical structure

Description

As a certified reference material (CRM), 2-Methylquinazolin-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.

2-Methylquinazolin-4-amine (CAS 3440-46-8) is a high-purity analytical reference standard with the molecular formula C9H9N3 and a molecular weight of 159.19 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-Methylquinazolin-4-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
