Chemical Structure
Description
Acetic acid ethenyl ester, polymer with 2,5-furandione and sodium ethenesulfonate (CAS 67893-24-7), molecular formula C2H3O3SC4H2O3C4H6O2Na and molecular weight 314.24 g/mol, is a CATO reference standard with documented purity and traceability.
Acetic acid ethenyl ester, polymer with 2,5-furandione and sodium ethenesulfonate (C2H3O3SC4H2O3C4H6O2Na) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures Acetic acid ethenyl ester, polymer with 2,5-furandione and sodium ethenesulfonate 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.
