Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 307.18 g/mol gives 5-Bromobenzo[c]phenanthrene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromobenzo[c]phenanthrene (CAS 89523-51-3) is a high-purity analytical reference standard with the molecular formula C18H11Br and a molecular weight of 307.18 g/mol.
Structurally, 5-Bromobenzo[c]phenanthrene (C18H11Br) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 307.18 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 5-Bromobenzo[c]phenanthrene 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.
