Description
CATO manufactures 4,4'-(Ethane-1,2-diylbis(azanediyl))dibenzoic acid 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.
CATO supplies 4,4'-(Ethane-1,2-diylbis(azanediyl))dibenzoic acid (CAS 95627-01-3), a certified reference material (molecular formula C16H16N2O4, MW 300.31 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-(Ethane-1,2-diylbis(azanediyl))dibenzoic acid (C16H16N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
