Chemical Structure
Description
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.
1143461-49-7 2-Chloro-5-(3-chloro-5-fluorophenyl)-1-pentene MFCD11915888 (CAS 1143461-49-7) is a high-purity analytical reference standard with the molecular formula C11H11Cl2F and a molecular weight of 233.11 g/mol.
1143461-49-7 2-Chloro-5-(3-chloro-5-fluorophenyl)-1-pentene MFCD11915888 (C11H11Cl2F) contains fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
