Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 498.68 g/mol gives trans-Bromdane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
trans-Bromdane (CAS 18300-04-4), molecular formula C10H6Br2Cl6 and molecular weight 498.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of trans-Bromdane (C10H6Br2Cl6) is characterized by chlorine/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.
As a certified reference material (CRM), trans-Bromdane 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.
