Chemical Structure

3-Bromo-5-methoxy-4-methylpyridine CAS 70201-49-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 202.05 g/mol gives 3-Bromo-5-methoxy-4-methylpyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Bromo-5-methoxy-4-methylpyridine (CAS 70201-49-9), a certified reference material (molecular formula C7H8BrNO, MW 202.05 g/mol) for analytical method development and quality control.

3-Bromo-5-methoxy-4-methylpyridine (C7H8BrNO) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 3-Bromo-5-methoxy-4-methylpyridine 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.
