Chemical Structure
Description
2-Propenoic acid, butyl ester, polymer with 1,1-dichloroethene and methyl 2-propenoate (CAS 25988-90-3), molecular formula C7H12O2C2H2Cl2C4H5O2 and molecular weight 310.19 g/mol, is a CATO reference standard with documented purity and traceability.
2-Propenoic acid, butyl ester, polymer with 1,1-dichloroethene and methyl 2-propenoate (C7H12O2C2H2Cl2C4H5O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
