Description
Compared with other compounds in its class, the molecular weight of 226.69 g/mol gives N2-(4-chlorophenyl)-1,3,4-thiadiazole-2,5-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N2-(4-chlorophenyl)-1,3,4-thiadiazole-2,5-diamine (CAS 21123-47-7), a certified reference material (molecular formula C8H7ClN4S, MW 226.69 g/mol) for analytical method development and quality control.
N2-(4-chlorophenyl)-1,3,4-thiadiazole-2,5-diamine (C8H7ClN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
