Chemical Structure
Description
2-Butenedioic acid (2E)-, polymer with ethene, 1,4-hexadiene and 1-propene (CAS 61615-63-2), molecular formula C4H4O4C8H12C3H6 and molecular weight 266.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Butenedioic acid (2E)-, polymer with ethene, 1,4-hexadiene and 1-propene (C4H4O4C8H12C3H6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
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.
