Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-1,1-difluorocyclopentane (CAS 2303705-25-9), molecular formula C5H7BrF2 and molecular weight 185.01 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H7BrF2, 2-Bromo-1,1-difluorocyclopentane contains fluorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 185.01 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.
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.
