Chemical Structure
Description
CATO supplies 5-((4,5-Dichloro-1H-imidazol-1-yl)methyl)-1,3,4-oxadiazole-2-thiol (CAS 175201-82-8), a certified reference material (molecular formula C6H4Cl2N4OS, MW 251.09 g/mol) for analytical method development and quality control.
5-((4,5-Dichloro-1H-imidazol-1-yl)methyl)-1,3,4-oxadiazole-2-thiol (C6H4Cl2N4OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
