Compared with other compounds in its class, the molecular weight of 263.21 g/mol gives 1-(Bromomethyl)-1-(sec-butoxy)cycloheptane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(Bromomethyl)-1-(sec-butoxy)cycloheptane (CAS 1251099-26-9), molecular formula C12H23BrO and molecular weight 263.21 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H23BrO, 1-(Bromomethyl)-1-(sec-butoxy)cycloheptane contains a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 263.21 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.
