Chemical Structure
Description
Triphenylantimony dibromide, 98+% (CAS 1538-59-6) is a high-purity analytical reference standard with the molecular formula C18H15Br2Sb and a molecular weight of 512.88 g/mol.
The molecular framework of Triphenylantimony dibromide, 98+% (C18H15Br2Sb) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Triphenylantimony dibromide, 98+% 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.
