Chemical Structure
Description
CATO supplies Butanedioic acid, 2-methylene-, polymer with ethenyl acetate and 1-ethenyl-2-pyrrolidinone (CAS 68928-72-3), a certified reference material (molecular formula C5H6O4C6H9NOC4H6O2, MW 327.33 g/mol) for analytical method development and quality control.
The molecular framework of Butanedioic acid, 2-methylene-, polymer with ethenyl acetate and 1-ethenyl-2-pyrrolidinone (C5H6O4C6H9NOC4H6O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
CATO manufactures Butanedioic acid, 2-methylene-, polymer with ethenyl acetate and 1-ethenyl-2-pyrrolidinone 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.
