Description

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.

cis-1,2-Dicyano-1,2-bis(2,4,5-trimethyl-3-thienyl)ethene (CAS 112440-46-7) is a high-purity analytical reference standard with the molecular formula C18H18N2S2 and a molecular weight of 326.48 g/mol.

Structurally, cis-1,2-Dicyano-1,2-bis(2,4,5-trimethyl-3-thienyl)ethene (C18H18N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 326.48 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
