2-(Thiophen-2-ylmethylene)malononitrile CAS 28162-32-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Thiophen-2-ylmethylene)malononitrile.

2-(Thiophen-2-ylmethylene)malononitrile (CAS 28162-32-5), molecular formula C8H4N2S and molecular weight 160.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H4N2S, 2-(Thiophen-2-ylmethylene)malononitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 160.20 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.
