4-Chloro-2-((3-chlorobenzyl)amino)thiazole-5-carbonitrile (CAS 866155-94-4), molecular formula C11H7Cl2N3S and molecular weight 284.16 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-2-((3-chlorobenzyl)amino)thiazole-5-carbonitrile (C11H7Cl2N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
