Description
CATO manufactures (2-Bromoprop-1-ene-1,1-diyl)dibenzene 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.
(2-Bromoprop-1-ene-1,1-diyl)dibenzene (CAS 781-32-8), molecular formula C15H13Br and molecular weight 273.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2-Bromoprop-1-ene-1,1-diyl)dibenzene (C15H13Br) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
