Chemical Structure

1,2-Dibenzylbenzene CAS 792-68-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 258.36 g/mol gives 1,2-Dibenzylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2-Dibenzylbenzene (CAS 792-68-7), molecular formula C20H18 and molecular weight 258.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,2-Dibenzylbenzene (C20H18) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
