Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(Bromomethyl)-3-ethylcyclobutane (CAS 1399664-45-9) is a high-purity analytical reference standard with the molecular formula C7H13Br and a molecular weight of 177.08 g/mol.
Based on its molecular formula C7H13Br, 1-(Bromomethyl)-3-ethylcyclobutane contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 177.08 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.
