Chemical Structure
Description
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.
2-Propenoic acid, methyl ester, polymer with 1,1-dichloroethene and 2-propenenitrile (CAS 24968-80-7) is a high-purity analytical reference standard with the molecular formula C2H2Cl2C4H6O2C3H3N and a molecular weight of 236.09 g/mol.
2-Propenoic acid, methyl ester, polymer with 1,1-dichloroethene and 2-propenenitrile (C2H2Cl2C4H6O2C3H3N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
