Chemical Structure
Description
The occurrence of 1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol and 1,2,3-propanetriol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol and 1,2,3-propanetriol (CAS 65970-35-6) is a high-purity analytical reference standard with the molecular formula C8Cl4O3C3H8O3C2H6O2 and a molecular weight of 440.05 g/mol.
1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol and 1,2,3-propanetriol (C8Cl4O3C3H8O3C2H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 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.
