Compared with other compounds in its class, the molecular weight of 100.50 g/mol gives 2-Chloro-1,1-difluoroethane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-1,1-difluoroethane (CAS 338-65-8) is a high-purity analytical reference standard with the molecular formula C2H3ClF2 and a molecular weight of 100.50 g/mol.
Based on its molecular formula C2H3ClF2, 2-Chloro-1,1-difluoroethane contains fluorine/chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 100.50 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.
