Chemical Structure
Description
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 supplies 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione, 1,2-propanediol and 1,2,3-propanetriol (CAS 65605-75-6), a certified reference material (molecular formula C8H4O3C4H2O3C3H8O3C3H8O2C2H6O2, MW 476.43 g/mol) for analytical method development and quality control.
The molecular framework of 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione, 1,2-propanediol and 1,2,3-propanetriol (C8H4O3C4H2O3C3H8O3C3H8O2C2H6O2) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione, 1,2-propanediol and 1,2,3-propanetriol 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.
