Acetic acid ethenyl ester, polymer with ethene, 2-propenamide and 2-propen-1-yl N-(hydroxymethyl)carbamate (CAS 40838-77-5), molecular formula C5H9NO3C4H6O2C3H5NOC2H4 and molecular weight 316.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Acetic acid ethenyl ester, polymer with ethene, 2-propenamide and 2-propen-1-yl N-(hydroxymethyl)carbamate (C5H9NO3C4H6O2C3H5NOC2H4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Acetic acid ethenyl ester, polymer with ethene, 2-propenamide and 2-propen-1-yl N-(hydroxymethyl)carbamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
