(E)-3-Isobutyl-2-mercapto-5-(thiophen-2-ylmethylene)-3,5-dihydro-4h-imidazol-4-one CAS 663203-91-6 chemical structure

Description

The occurrence of (E)-3-Isobutyl-2-mercapto-5-(thiophen-2-ylmethylene)-3,5-dihydro-4h-imidazol-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-3-Isobutyl-2-mercapto-5-(thiophen-2-ylmethylene)-3,5-dihydro-4h-imidazol-4-one (CAS 663203-91-6) is a high-purity analytical reference standard with the molecular formula C12H14N2OS2 and a molecular weight of 266.38 g/mol.

The molecular framework of (E)-3-Isobutyl-2-mercapto-5-(thiophen-2-ylmethylene)-3,5-dihydro-4h-imidazol-4-one (C12H14N2OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 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.
