CATO supplies 1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol and 2,5-furandione (CAS 29403-69-8), a certified reference material (molecular formula C8Cl4O3C4H2O3C2H6O2, MW 446.01 g/mol) for analytical method development and quality control.
The molecular framework of 1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol and 2,5-furandione (C8Cl4O3C4H2O3C2H6O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
CATO manufactures 1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol and 2,5-furandione 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.
