(E)-2-(1H-Benzo[d]imidazol-2-yl)-3-(thiophen-2-yl)acrylonitrile CAS 104030-31-1

Description

(E)-2-(1H-Benzo[d]imidazol-2-yl)-3-(thiophen-2-yl)acrylonitrile (CAS 104030-31-1), molecular formula C14H9N3S and molecular weight 251.31 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (E)-2-(1H-Benzo[d]imidazol-2-yl)-3-(thiophen-2-yl)acrylonitrile (C14H9N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 251.31 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
