Chemical Structure

1,2-Diphenylcyclobuta[b]anthracene CAS 49626-41-7 chemical structure

Description

1,2-Diphenylcyclobuta[b]anthracene (CAS 49626-41-7) is a high-purity analytical reference standard with the molecular formula C28H18 and a molecular weight of 354.44 g/mol.

The molecular framework of 1,2-Diphenylcyclobuta[b]anthracene (C28H18) is characterized by 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 1,2-Diphenylcyclobuta[b]anthracene 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.
