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-(3-Bromo-2-methylpropyl)-4-methylcyclohexane (CAS 2808-52-8), molecular formula C11H21Br and molecular weight 233.19 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H21Br, 1-(3-Bromo-2-methylpropyl)-4-methylcyclohexane contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 233.19 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.
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.
