Chemical Structure
Description
(5E)-2-Mercapto-3-phenyl-5-(1H-pyrrol-2-ylmethylene)-3,5-dihydro-4H-imidazol-4-one (C14H11N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(5E)-2-Mercapto-3-phenyl-5-(1H-pyrrol-2-ylmethylene)-3,5-dihydro-4H-imidazol-4-one (CAS 890546-87-9) is a high-purity analytical reference standard with the molecular formula C14H11N3OS and a molecular weight of 269.32 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
