Description
CATO supplies 2-Butenedioic acid (2E)-, 1,4-dibutyl ester, polymer with ethenyl acetate (CAS 25989-00-8), a certified reference material (molecular formula C12H20O4C4H6O2, MW 314.38 g/mol) for analytical method development and quality control.
The molecular framework of 2-Butenedioic acid (2E)-, 1,4-dibutyl ester, polymer with ethenyl acetate (C12H20O4C4H6O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
