Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 281.15 g/mol gives 1-Bromopyrene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromopyrene (CAS 1714-29-0), molecular formula C16H9Br and molecular weight 281.15 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromopyrene (C16H9Br) 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. 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 1-Bromopyrene 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.
