2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenylbenzene CAS 26336-23-2

Description

The occurrence of 2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenylbenzene is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenylbenzene (CAS 26336-23-2), molecular formula C12H20O4C8H8 and molecular weight 332.44 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H20O4C8H8, 2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenylbenzene contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 332.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
