Chemical Structure
Description
The occurrence of 2,2-Dibromocyclobutan-1-one is closely related to a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,2-Dibromocyclobutan-1-one (CAS 2885-97-4), molecular formula C4H4Br2O and molecular weight 227.88 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H4Br2O, 2,2-Dibromocyclobutan-1-one 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 227.88 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2-Dibromocyclobutan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
