Description
As a certified reference material (CRM), 2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with 1,4-dioctyl (2Z)-2-butenedioate and ethenyl acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with 1,4-dioctyl (2Z)-2-butenedioate and ethenyl acetate (CAS 58923-93-6), molecular formula C20H34O4C12H20O4C4H6O2 and molecular weight 652.87 g/mol, is a CATO reference standard with documented purity and traceability.
2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with 1,4-dioctyl (2Z)-2-butenedioate and ethenyl acetate (C20H34O4C12H20O4C4H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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.
