2-Propenoic acid, 2-methyl-, methyl ester, polymer with butyl 2-propenoate (CAS 25852-37-3), molecular formula C7H12O2C5H8O2 and molecular weight 228.29 g/mol, is a CATO reference standard with documented purity and traceability.
2-Propenoic acid, 2-methyl-, methyl ester, polymer with butyl 2-propenoate (C7H12O2C5H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-Propenoic acid, 2-methyl-, methyl ester, polymer with butyl 2-propenoate 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.
