As a certified reference material (CRM), (5Z)-5-{[3-(4-cyclohexylphenyl)-1-phenyl-1H-pyrazol-4-yl]methylidene}-2-sulfanylidene-1,3-thiazolidin-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.
CATO supplies (5Z)-5-{[3-(4-cyclohexylphenyl)-1-phenyl-1H-pyrazol-4-yl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one (CAS 956206-76-1), a certified reference material (molecular formula C25H23N3OS2, MW 445.60 g/mol) for analytical method development and quality control.
(5Z)-5-{[3-(4-cyclohexylphenyl)-1-phenyl-1H-pyrazol-4-yl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one (C25H23N3OS2) contains a steroid core, 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.
