(E)-3-(but-2-en-1-yl)dihydrofuran-2,5-dione CAS 7538-42-3

Description

The occurrence of (E)-3-(but-2-en-1-yl)dihydrofuran-2,5-dione 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.

(E)-3-(but-2-en-1-yl)dihydrofuran-2,5-dione (CAS 7538-42-3), molecular formula C8H10O3 and molecular weight 154.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-3-(but-2-en-1-yl)dihydrofuran-2,5-dione (C8H10O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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 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), (E)-3-(but-2-en-1-yl)dihydrofuran-2,5-dione 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.
