2-((4-Fluorobenzyl)thio)-4,5-diisobutyl-1-propyl-1H-imidazole CAS 338966-18-0

Description

The occurrence of 2-((4-Fluorobenzyl)thio)-4,5-diisobutyl-1-propyl-1H-imidazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((4-Fluorobenzyl)thio)-4,5-diisobutyl-1-propyl-1H-imidazole (CAS 338966-18-0), molecular formula C21H31FN2S and molecular weight 362.55 g/mol, is a CATO reference standard with documented purity and traceability.

2-((4-Fluorobenzyl)thio)-4,5-diisobutyl-1-propyl-1H-imidazole (C21H31FN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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 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.
