Chemical Structure

4-Bromo-5-chloropyridin-3-ol CAS 1211517-85-9 chemical structure

Description

The occurrence of 4-Bromo-5-chloropyridin-3-ol is closely related to 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.

4-Bromo-5-chloropyridin-3-ol (CAS 1211517-85-9) is a high-purity analytical reference standard with the molecular formula C5H3BrClNO and a molecular weight of 208.44 g/mol.

Based on its molecular formula C5H3BrClNO, 4-Bromo-5-chloropyridin-3-ol contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
