Chemical Structure

(2E,4E)-Undeca-2,4-dienal CAS 13162-46-4 chemical structure

Description

(2E,4E)-Undeca-2,4-dienal (CAS 13162-46-4) is a high-purity analytical reference standard with the molecular formula C11H18O and a molecular weight of 166.26 g/mol.

Based on its molecular formula C11H18O, (2E,4E)-Undeca-2,4-dienal contains a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 166.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
