Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,7-Dibromo-9,9-bis(3-(tert-butyl propanoate))fluorene.
CATO supplies 2,7-Dibromo-9,9-bis(3-(tert-butyl propanoate))fluorene (CAS 1030632-69-9), a certified reference material (molecular formula C27H32Br2O4, MW 580.35 g/mol) for analytical method development and quality control.
2,7-Dibromo-9,9-bis(3-(tert-butyl propanoate))fluorene (C27H32Br2O4) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 2,7-Dibromo-9,9-bis(3-(tert-butyl propanoate))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.
