Chemical Structure

n-heptyltriphenylphosphonium bromide CAS 13423-48-8 chemical structure

Description

CATO manufactures n-heptyltriphenylphosphonium bromide 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.

n-heptyltriphenylphosphonium bromide (CAS 13423-48-8), molecular formula C25H48PBr and molecular weight 459.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of n-heptyltriphenylphosphonium bromide (C25H48PBr) is characterized by organophosphorus functionality, bromine substitution. 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.

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.
