2-Bromo-4-hydroxy-5-methoxyisophthalaldehyde CAS 1498322-37-4

Description

The occurrence of 2-Bromo-4-hydroxy-5-methoxyisophthalaldehyde is closely related to a carboxylic acid 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.

2-Bromo-4-hydroxy-5-methoxyisophthalaldehyde (CAS 1498322-37-4), molecular formula C9H7BrO4 and molecular weight 259.05 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H7BrO4, 2-Bromo-4-hydroxy-5-methoxyisophthalaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 259.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2-Bromo-4-hydroxy-5-methoxyisophthalaldehyde 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.
