Chemical Structure
Description
1,1'-(9H-Fluorene-2,7-diyl)bis(4-chlorobutan-1-one) (CAS 34927-52-1) is a high-purity analytical reference standard with the molecular formula C21H20Cl2O2 and a molecular weight of 375.29 g/mol.
1,1'-(9H-Fluorene-2,7-diyl)bis(4-chlorobutan-1-one) (C21H20Cl2O2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine 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.
CATO manufactures 1,1'-(9H-Fluorene-2,7-diyl)bis(4-chlorobutan-1-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.
