Chemical Structure
Description
The occurrence of Ethyl acrylate-methacrylic acid-methyl methacrylate copolymer is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl acrylate-methacrylic acid-methyl methacrylate copolymer (CAS 25133-97-5), a certified reference material (molecular formula C5H8O2C4H6O2, MW 186.21 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl acrylate-methacrylic acid-methyl methacrylate copolymer (C5H8O2C4H6O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
