2-Bromo-9-(naphthalen-2-yl)-9-phenyl-9H-fluorene CAS 1345860-68-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-9-(naphthalen-2-yl)-9-phenyl-9H-fluorene.

2-Bromo-9-(naphthalen-2-yl)-9-phenyl-9H-fluorene (CAS 1345860-68-5), molecular formula C29H19Br and molecular weight 447.37 g/mol, is a CATO reference standard with documented purity and traceability.

2-Bromo-9-(naphthalen-2-yl)-9-phenyl-9H-fluorene (C29H19Br) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
