Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
9-Bromo-2,6-di-tert-butylanthracene (CAS 62337-63-7), molecular formula C22H25Br and molecular weight 369.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9-Bromo-2,6-di-tert-butylanthracene (C22H25Br) is characterized by bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
