Chemical Structure
Description
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.
2-Propenoic acid, 2-hydroxyethyl ester, polymer with 1,1-dichloroethene and methyl 2-propenoate (CAS 63744-63-8) is a high-purity analytical reference standard with the molecular formula C5H8O3C2H2Cl2C4H6O2 and a molecular weight of 299.14 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Propenoic acid, 2-hydroxyethyl ester, polymer with 1,1-dichloroethene and methyl 2-propenoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
