Description
CATO supplies 2,7-Bis[2,6-bis(1-methylethyl)phenyl]-4,5,9,10-tetrabromobenzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetrone (CAS 943148-75-2), a certified reference material (molecular formula C38H34Br4N2O4, MW 902.30 g/mol) for analytical method development and quality control.
Structurally, 2,7-Bis[2,6-bis(1-methylethyl)phenyl]-4,5,9,10-tetrabromobenzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetrone (C38H34Br4N2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 902.30 g/mol, it falls into the high-molecular-weight range. 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), 2,7-Bis[2,6-bis(1-methylethyl)phenyl]-4,5,9,10-tetrabromobenzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetrone 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.
