Chemical Structure
Description
The occurrence of (Z)-5-bromo-2-hydroxy-3-methoxybenzaldehyde O-methyl oxime 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.
CATO supplies (Z)-5-bromo-2-hydroxy-3-methoxybenzaldehyde O-methyl oxime (CAS 338416-57-2), a certified reference material (molecular formula C9H10BrNO3, MW 260.08 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H10BrNO3, (Z)-5-bromo-2-hydroxy-3-methoxybenzaldehyde O-methyl oxime 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 260.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
