Chemical Structure
Description
The occurrence of 2-Butenedioic acid (2E)-, polymer with 1,3-butadiene, ethenylbenzene and 2-methylenebutanedioic acid 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.
CATO supplies 2-Butenedioic acid (2E)-, polymer with 1,3-butadiene, ethenylbenzene and 2-methylenebutanedioic acid (CAS 49716-81-6), a certified reference material (molecular formula C5H6O4C4H4O4C8H8C4H6, MW 404.42 g/mol) for analytical method development and quality control.
Structurally, 2-Butenedioic acid (2E)-, polymer with 1,3-butadiene, ethenylbenzene and 2-methylenebutanedioic acid (C5H6O4C4H4O4C8H8C4H6) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 404.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 2-Butenedioic acid (2E)-, polymer with 1,3-butadiene, ethenylbenzene and 2-methylenebutanedioic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation.
