Chemical Structure

Di-p-tolylmethane CAS 4957-14-6 chemical structure

Description

Di-p-tolylmethane (CAS 4957-14-6) is a high-purity analytical reference standard with the molecular formula C15H16 and a molecular weight of 196.29 g/mol.

Based on its molecular formula C15H16, Di-p-tolylmethane contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 196.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
