Chemical Structure
Description
Bis(2-Ethylhexyl) Tetrabromophthalate (CAS 26040-51-7), molecular formula C24H34Br4O4 and molecular weight 706.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(2-Ethylhexyl) Tetrabromophthalate (C24H34Br4O4) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Bis(2-Ethylhexyl) Tetrabromophthalate 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.
