Chemical Structure
Description
3-(2,5-Dimethylphenyl)-1-(2-(methylthio)phenyl)propan-1-one (CAS 898794-98-4), molecular formula C18H20OS and molecular weight 284.42 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2,5-Dimethylphenyl)-1-(2-(methylthio)phenyl)propan-1-one (C18H20OS) contains a steroid core, 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), 3-(2,5-Dimethylphenyl)-1-(2-(methylthio)phenyl)propan-1-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.
