(2-((2,5-Dimethylbenzyl)thio)-4,5-dihydro-1H-imidazol-1-yl)(2-fluorophenyl)methanone CAS 851804-45-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-((2,5-Dimethylbenzyl)thio)-4,5-dihydro-1H-imidazol-1-yl)(2-fluorophenyl)methanone.

(2-((2,5-Dimethylbenzyl)thio)-4,5-dihydro-1H-imidazol-1-yl)(2-fluorophenyl)methanone (CAS 851804-45-0), molecular formula C19H19FN2OS and molecular weight 342.43 g/mol, is a CATO reference standard with documented purity and traceability.

(2-((2,5-Dimethylbenzyl)thio)-4,5-dihydro-1H-imidazol-1-yl)(2-fluorophenyl)methanone (C19H19FN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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.

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.
