2-Propenoic acid, polymer with ethyl 2-propenoate, 2-propenal and 2-propenenitrile (C5H8O2C3H4O2C3H4OC3H3N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-Propenoic acid, polymer with ethyl 2-propenoate, 2-propenal and 2-propenenitrile (CAS 66028-07-7), molecular formula C5H8O2C3H4O2C3H4OC3H3N and molecular weight 281.31 g/mol, is a CATO reference standard with documented purity and traceability.
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.
