Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 513.76 g/mol gives 5,6,7,8-Tetrabromo-1H,3H-benzo[de]isochromene-1,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5,6,7,8-Tetrabromo-1H,3H-benzo[de]isochromene-1,3-dione (CAS 2114416-27-0) is a high-purity analytical reference standard with the molecular formula C12H2Br4O3 and a molecular weight of 513.76 g/mol.
The molecular framework of 5,6,7,8-Tetrabromo-1H,3H-benzo[de]isochromene-1,3-dione (C12H2Br4O3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 5,6,7,8-Tetrabromo-1H,3H-benzo[de]isochromene-1,3-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
