Description
As a certified reference material (CRM), 2’,7’-Dibromo-2-vinylspiro[cyclopropane-1,9’-fluorene] 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.
CATO supplies 2’,7’-Dibromo-2-vinylspiro[cyclopropane-1,9’-fluorene] (CAS 951884-03-0), a certified reference material (molecular formula C17H12Br2, MW 376.09 g/mol) for analytical method development and quality control.
2’,7’-Dibromo-2-vinylspiro[cyclopropane-1,9’-fluorene] (C17H12Br2) contains bromine substitution, a polycyclic aromatic system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
