Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 244.10 g/mol gives (1r,3r)-3-(3-Bromo-4-fluorophenyl)cyclobutan-1-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(1r,3r)-3-(3-Bromo-4-fluorophenyl)cyclobutan-1-amine (CAS 1807936-49-7), molecular formula C10H11BrFN and molecular weight 244.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H11BrFN, (1r,3r)-3-(3-Bromo-4-fluorophenyl)cyclobutan-1-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 244.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
