Description
CATO manufactures 1,3,7-Tribromo-9H-fluoren-2-amine 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.
1,3,7-Tribromo-9H-fluoren-2-amine (CAS 724-31-2), molecular formula C13H8Br3N and molecular weight 417.92 g/mol, is a CATO reference standard with documented purity and traceability.
1,3,7-Tribromo-9H-fluoren-2-amine (C13H8Br3N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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.
