Description
CATO supplies 1,1'-(4,4',5,5'-Tetrachloro[1,3'-bi-1H-pyrrole]-2,2'-diyl)bis[1-(2-hydroxyphenyl)methanone] (CAS 1227962-62-0), a certified reference material (molecular formula C22H12Cl4N2O4, MW 510.15 g/mol) for analytical method development and quality control.
The molecular framework of 1,1'-(4,4',5,5'-Tetrachloro[1,3'-bi-1H-pyrrole]-2,2'-diyl)bis[1-(2-hydroxyphenyl)methanone] (C22H12Cl4N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
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.
CATO manufactures 1,1'-(4,4',5,5'-Tetrachloro[1,3'-bi-1H-pyrrole]-2,2'-diyl)bis[1-(2-hydroxyphenyl)methanone] under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
