Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Butenedioic acid (2Z)-, 1,4-dioctyl ester, polymer with ethenyl acetate and 2-ethylhexyl 2-propenoate (CAS 25280-35-7), a certified reference material (molecular formula C20H36O4C11H20O2C4H6O2, MW 610.87 g/mol) for analytical method development and quality control.
Structurally, 2-Butenedioic acid (2Z)-, 1,4-dioctyl ester, polymer with ethenyl acetate and 2-ethylhexyl 2-propenoate (C20H36O4C11H20O2C4H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 610.87 g/mol, it falls into the high-molecular-weight range. 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).
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.
