Chemical Structure

3,5-Diphenyl-1-(m-tolyl)formazan CAS 71274-65-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 314.38 g/mol gives 3,5-Diphenyl-1-(m-tolyl)formazan distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5-Diphenyl-1-(m-tolyl)formazan (CAS 71274-65-2) is a high-purity analytical reference standard with the molecular formula C20H18N4 and a molecular weight of 314.38 g/mol.

Based on its molecular formula C20H18N4, 3,5-Diphenyl-1-(m-tolyl)formazan contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 314.38 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), 3,5-Diphenyl-1-(m-tolyl)formazan 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.
