Chemical Structure

DI o-tolylmethane CAS 1634-74-8 chemical structure

Description

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

DI o-tolylmethane (CAS 1634-74-8) 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 o-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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), DI o-tolylmethane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
