Chemical Structure

3,4’-dimethylbiphenyl CAS 7383-90-6 chemical structure

Description

Owing to a polycyclic aromatic system, 3,4’-dimethylbiphenyl 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

3,4’-dimethylbiphenyl (CAS 7383-90-6), molecular formula C14H14 and molecular weight 182.26 g/mol, is a CATO reference standard with documented purity and traceability.

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.
