Chemical Structure

5-Bromo-4-methoxy-6-methylquinazoline CAS 2387928-22-3 chemical structure

Description

The occurrence of 5-Bromo-4-methoxy-6-methylquinazoline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-4-methoxy-6-methylquinazoline (CAS 2387928-22-3), molecular formula C10H9BrN2O and molecular weight 253.10 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H9BrN2O, 5-Bromo-4-methoxy-6-methylquinazoline contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 5-Bromo-4-methoxy-6-methylquinazoline 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.
