7-Bromo-4-chloro-6-methoxyquinazoline CAS 1256955-34-6

Description

The occurrence of 7-Bromo-4-chloro-6-methoxyquinazoline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Bromo-4-chloro-6-methoxyquinazoline (CAS 1256955-34-6) is a high-purity analytical reference standard with the molecular formula C9H6BrClN2O and a molecular weight of 273.51 g/mol.

7-Bromo-4-chloro-6-methoxyquinazoline (C9H6BrClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
