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.
1,3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-, polymer with 1,2-ethanediol and 2,5-furandione (CAS 25749-55-7), molecular formula C8H8O3C4H2O3C2H6O2 and molecular weight 312.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-, polymer with 1,2-ethanediol and 2,5-furandione (C8H8O3C4H2O3C2H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 312.27 g/mol, it falls into the moderately-high-molecular-weight range. 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, 3a,4,7,7a-tetrahydro-, 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.
