The occurrence of 5-Bromo-4-methoxy-6-methylpyrimidin-2-amine is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-4-methoxy-6-methylpyrimidin-2-amine (CAS 7749-55-5) is a high-purity analytical reference standard with the molecular formula C6H8BrN3O and a molecular weight of 218.05 g/mol.
The molecular framework of 5-Bromo-4-methoxy-6-methylpyrimidin-2-amine (C6H8BrN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
