Description
The occurrence of 2,2'-[(3,3'-Dimethoxy-4,4'-biphenyldiyl)bis(imino-2,1-ethanediyl)]bis(1,3,3-trimethyl-3H-indolium) ditetrafluoroborate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,2'-[(3,3'-Dimethoxy-4,4'-biphenyldiyl)bis(imino-2,1-ethanediyl)]bis(1,3,3-trimethyl-3H-indolium) ditetrafluoroborate (CAS 85391-36-2), molecular formula C40H48N4O2BF4 and molecular weight 703.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,2'-[(3,3'-Dimethoxy-4,4'-biphenyldiyl)bis(imino-2,1-ethanediyl)]bis(1,3,3-trimethyl-3H-indolium) ditetrafluoroborate (C40H48N4O2BF4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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), 2,2'-[(3,3'-Dimethoxy-4,4'-biphenyldiyl)bis(imino-2,1-ethanediyl)]bis(1,3,3-trimethyl-3H-indolium) ditetrafluoroborate meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
