1,2,4,5-Tetrabromo-3,6-dimethoxybenzene CAS 19403-94-2

Description

Compared with other compounds in its class, the molecular weight of 453.75 g/mol gives 1,2,4,5-Tetrabromo-3,6-dimethoxybenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2,4,5-Tetrabromo-3,6-dimethoxybenzene (CAS 19403-94-2), molecular formula C8H6Br4O2 and molecular weight 453.75 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,2,4,5-Tetrabromo-3,6-dimethoxybenzene (C8H6Br4O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
