Chemical Structure

2-Butenedioic acid (2E)-, polymer with 2,2-dimethyl-1,3-propanediol and 2,5-furandione CAS 65605-78-9 chemical structure

Description

The occurrence of 2-Butenedioic acid (2E)-, polymer with 2,2-dimethyl-1,3-propanediol and 2,5-furandione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Butenedioic acid (2E)-, polymer with 2,2-dimethyl-1,3-propanediol and 2,5-furandione (CAS 65605-78-9), a certified reference material (molecular formula C4H4O4C5H12O2C4H2O3, MW 318.28 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Butenedioic acid (2E)-, polymer with 2,2-dimethyl-1,3-propanediol and 2,5-furandione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.28 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), 2-Butenedioic acid (2E)-, polymer with 2,2-dimethyl-1,3-propanediol and 2,5-furandione 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.
