Chemical Structure

3-Ethylbiphenyl CAS 5668-93-9 chemical structure

Description

The occurrence of 3-Ethylbiphenyl is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Ethylbiphenyl (CAS 5668-93-9) is a high-purity analytical reference standard with the molecular formula C14H14 and a molecular weight of 182.26 g/mol.

Owing to a polycyclic aromatic system, 3-Ethylbiphenyl is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 182.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
