Compared with other compounds in its class, the molecular weight of 356.33 g/mol gives 2-Propenoic acid, polymer with ethenyl acetate, ethyl 2-propenoate and 2,5-furandione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Propenoic acid, polymer with ethenyl acetate, ethyl 2-propenoate and 2,5-furandione (CAS 65859-38-3), molecular formula C5H8O2C4H2O3C4H6O2C3H4O2 and molecular weight 356.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2-Propenoic acid, polymer with ethenyl acetate, ethyl 2-propenoate and 2,5-furandione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.33 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.
CATO manufactures 2-Propenoic acid, polymer with ethenyl acetate, ethyl 2-propenoate and 2,5-furandione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
