1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 1,2-propanediol CAS 26588-55-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 1,2-propanediol.

1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 1,2-propanediol (CAS 26588-55-6), molecular formula C8H4O3C4H2O3C3H8O2C2H6O2 and molecular weight 384.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 1,2-propanediol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 1,2-propanediol 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.
