Chemical Structure

2-(2-Phenyl-4H-thiochromen-4-ylidene)malononitrile CAS 15058-08-9 chemical structure

Description

The occurrence of 2-(2-Phenyl-4H-thiochromen-4-ylidene)malononitrile 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.

2-(2-Phenyl-4H-thiochromen-4-ylidene)malononitrile (CAS 15058-08-9), molecular formula C18H10N2S and molecular weight 286.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(2-Phenyl-4H-thiochromen-4-ylidene)malononitrile (C18H10N2S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 2-(2-Phenyl-4H-thiochromen-4-ylidene)malononitrile 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.
