(5E,8E,11E,14E)-10,10-Difluoroicosa-5,8,11,14-Tetraenoic Acid CAS 108212-58-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5E,8E,11E,14E)-10,10-Difluoroicosa-5,8,11,14-Tetraenoic Acid.

(5E,8E,11E,14E)-10,10-Difluoroicosa-5,8,11,14-Tetraenoic Acid (CAS 108212-58-4) is a high-purity analytical reference standard with the molecular formula C20H30F2O2 and a molecular weight of 340.45 g/mol.

Based on its molecular formula C20H30F2O2, (5E,8E,11E,14E)-10,10-Difluoroicosa-5,8,11,14-Tetraenoic Acid contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
