Chemical Structure
Description
Structurally, Tris(4-bromophenyl)phosphane (C18H12Br3P) contains organophosphorus functionality, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 498.97 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Tris(4-bromophenyl)phosphane (CAS 29949-81-3) is a high-purity analytical reference standard with the molecular formula C18H12Br3P and a molecular weight of 498.97 g/mol.
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 Tris(4-bromophenyl)phosphane 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.
