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, butyl ester, polymer with 1,1-dichloroethene and 2-ethoxyethyl 2-propenoate (CAS 71426-97-6) is a high-purity analytical reference standard with the molecular formula C7H12O3C7H12O2C2H2Cl2 and a molecular weight of 369.28 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Propenoic acid, butyl ester, polymer with 1,1-dichloroethene and 2-ethoxyethyl 2-propenoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures 2-Propenoic acid, butyl ester, polymer with 1,1-dichloroethene and 2-ethoxyethyl 2-propenoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
