Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 146.95 g/mol gives 2,3-Dichloro-3,3-difluoropropene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,3-Dichloro-3,3-difluoropropene (CAS 2252-87-1), a certified reference material (molecular formula C3H2Cl2F2, MW 146.95 g/mol) for analytical method development and quality control.
Based on its molecular formula C3H2Cl2F2, 2,3-Dichloro-3,3-difluoropropene contains fluorine/chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 146.95 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.
