Chemical Structure
Description
The occurrence of Tetrakis(4-bromophenyl)methane is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tetrakis(4-bromophenyl)methane (CAS 105309-59-9), molecular formula C25H16Br4 and molecular weight 636.01 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tetrakis(4-bromophenyl)methane (C25H16Br4) is characterized by bromine substitution, a polycyclic aromatic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Tetrakis(4-bromophenyl)methane 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.
