Chemical Structure
Description
The occurrence of 2-((1-(4-Fluorophenyl)ethylidene)hydrazineylidene)-3-(furan-2-ylmethyl)-4-phenyl-2,3-dihydrothiazole is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-((1-(4-Fluorophenyl)ethylidene)hydrazineylidene)-3-(furan-2-ylmethyl)-4-phenyl-2,3-dihydrothiazole (CAS 402945-83-9), a certified reference material (molecular formula C22H18FN3OS, MW 391.46 g/mol) for analytical method development and quality control.
2-((1-(4-Fluorophenyl)ethylidene)hydrazineylidene)-3-(furan-2-ylmethyl)-4-phenyl-2,3-dihydrothiazole (C22H18FN3OS) 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 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.
