Chemical Structure
Description
1-Bromo-3-(bromomethyl)adamantane (CAS 1822-25-9), molecular formula C11H16Br2 and molecular weight 308.05 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-3-(bromomethyl)adamantane (C11H16Br2) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 308.05 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
