Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.12 g/mol gives 10-Bromophenanthren-9-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 10-Bromophenanthren-9-ol (CAS 4120-76-7), a certified reference material (molecular formula C14H9BrO, MW 273.12 g/mol) for analytical method development and quality control.
The molecular framework of 10-Bromophenanthren-9-ol (C14H9BrO) is characterized by a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
