The occurrence of 1-Chloro-2,3,3,4,4,5,5-heptafluorocyclopent-1-ene is closely related to fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Chloro-2,3,3,4,4,5,5-heptafluorocyclopent-1-ene (CAS 1759-63-3), molecular formula C5ClF7 and molecular weight 228.50 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5ClF7, 1-Chloro-2,3,3,4,4,5,5-heptafluorocyclopent-1-ene contains fluorine/chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 228.50 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.
