Description
As a certified reference material (CRM), 3',6'-Dibromo-2,2'',4,4''-tetramethyl-[1,1':4',1''-terphenyl]-2',5'-diyl bis(2-((2-isopropyl-5-methylcyclohexyl)oxy)acetate) 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.
3',6'-Dibromo-2,2'',4,4''-tetramethyl-[1,1':4',1''-terphenyl]-2',5'-diyl bis(2-((2-isopropyl-5-methylcyclohexyl)oxy)acetate) (CAS 5465-55-4), molecular formula C46H59Br2O6 and molecular weight 867.77 g/mol, is a CATO reference standard with documented purity and traceability.
3',6'-Dibromo-2,2'',4,4''-tetramethyl-[1,1':4',1''-terphenyl]-2',5'-diyl bis(2-((2-isopropyl-5-methylcyclohexyl)oxy)acetate) (C46H59Br2O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
