Chemical Structure

5-Benzylidene-3-(phenylamino)-2-thioxoimidazolidin-4-one CAS 821781-86-6 chemical structure

Description

5-Benzylidene-3-(phenylamino)-2-thioxoimidazolidin-4-one (CAS 821781-86-6), molecular formula C16H13N3OS and molecular weight 295.36 g/mol, is a CATO reference standard with documented purity and traceability.

5-Benzylidene-3-(phenylamino)-2-thioxoimidazolidin-4-one (C16H13N3OS) 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.

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.

As a certified reference material (CRM), 5-Benzylidene-3-(phenylamino)-2-thioxoimidazolidin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
