3-((Diphenylmethylene)amino)-5-methylthiophene-2-carbonitrile CAS 948015-48-3

Description

The occurrence of 3-((Diphenylmethylene)amino)-5-methylthiophene-2-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-((Diphenylmethylene)amino)-5-methylthiophene-2-carbonitrile (CAS 948015-48-3), molecular formula C19H14N2S and molecular weight 302.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-((Diphenylmethylene)amino)-5-methylthiophene-2-carbonitrile (C19H14N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-((Diphenylmethylene)amino)-5-methylthiophene-2-carbonitrile 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.
