Chemical Structure
Description
2-Butenedioic acid (2Z)-, 1,4-bis(2-ethylhexyl) ester, polymer with ethenyl acetate and ethyl 2-propenoate (CAS 24938-15-6), molecular formula C20H36O4C5H8O2C4H6O2 and molecular weight 526.71 g/mol, is a CATO reference standard with documented purity and traceability.
2-Butenedioic acid (2Z)-, 1,4-bis(2-ethylhexyl) ester, polymer with ethenyl acetate and ethyl 2-propenoate (C20H36O4C5H8O2C4H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Butenedioic acid (2Z)-, 1,4-bis(2-ethylhexyl) ester, polymer with ethenyl acetate and ethyl 2-propenoate 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.
