Chemical Structure
Description
The occurrence of 2-Chloro-3-(4-chloro-3-fluorophenyl)-1-propene is closely related to fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-3-(4-chloro-3-fluorophenyl)-1-propene (CAS 951888-20-3) is a high-purity analytical reference standard with the molecular formula C9H7Cl2F and a molecular weight of 205.06 g/mol.
2-Chloro-3-(4-chloro-3-fluorophenyl)-1-propene (C9H7Cl2F) contains fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
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.
