Chemical Structure
Description
The occurrence of 8-Bromospiro[4.5]decane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
8-Bromospiro[4.5]decane (CAS 1602918-79-5) is a high-purity analytical reference standard with the molecular formula C10H17Br and a molecular weight of 217.15 g/mol.
8-Bromospiro[4.5]decane (C10H17Br) contains bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
