5-((4-Chlorophenyl)thio)-4-((2,6-dichlorophenoxy)methyl)-1-methyl-3-phenyl-1H-pyrazole CAS 318248-34-9

Description

5-((4-Chlorophenyl)thio)-4-((2,6-dichlorophenoxy)methyl)-1-methyl-3-phenyl-1H-pyrazole (CAS 318248-34-9) is a high-purity analytical reference standard with the molecular formula C23H17Cl3N2OS and a molecular weight of 475.82 g/mol.

5-((4-Chlorophenyl)thio)-4-((2,6-dichlorophenoxy)methyl)-1-methyl-3-phenyl-1H-pyrazole (C23H17Cl3N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
