Chemical Structure
Description
2-CHloro-1,1,1,3-tetrafluorobut-2-ene (CAS 885276-06-2), molecular formula C4H3ClF4 and molecular weight 162.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-CHloro-1,1,1,3-tetrafluorobut-2-ene (C4H3ClF4) is characterized by fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
