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.
1,3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-, polymer with 2,2-bis(bromomethyl)-1,3-propanediol, 1,2-ethanediol and 2,5-furandione, brominated (CAS 71549-87-6) is a high-purity analytical reference standard with the molecular formula C5H10Br2O2C8H8O3C4H2O3C2H6O2 and a molecular weight of 574.21 g/mol.
The molecular framework of 1,3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-, polymer with 2,2-bis(bromomethyl)-1,3-propanediol, 1,2-ethanediol and 2,5-furandione, brominated (C5H10Br2O2C8H8O3C4H2O3C2H6O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring 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 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).
As a certified reference material (CRM), 1,3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-, polymer with 2,2-bis(bromomethyl)-1,3-propanediol, 1,2-ethanediol and 2,5-furandione, brominated meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
