Chemical Structure
Description
3-Bromobicyclo[2.2.2]octan-2-one (CAS 1706432-81-6), molecular formula C8H11BrO and molecular weight 203.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, bromine substitution, 3-Bromobicyclo[2.2.2]octan-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 3-Bromobicyclo[2.2.2]octan-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
