Chemical Structure
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'-Dibromospiro[adamantane-2,9'-fluorene].
2',7'-Dibromospiro[adamantane-2,9'-fluorene] (CAS 727730-32-7), molecular formula C22H20Br2 and molecular weight 444.20 g/mol, is a CATO reference standard with documented purity and traceability.
2',7'-Dibromospiro[adamantane-2,9'-fluorene] (C22H20Br2) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2',7'-Dibromospiro[adamantane-2,9'-fluorene] 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.
