5-(4-Chlorophenyl)-N-(4-fluorophenyl)-1,3,4-thiadiazol-2-amine CAS 791788-59-5

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, 5-(4-Chlorophenyl)-N-(4-fluorophenyl)-1,3,4-thiadiazol-2-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

5-(4-Chlorophenyl)-N-(4-fluorophenyl)-1,3,4-thiadiazol-2-amine (CAS 791788-59-5), molecular formula C14H9ClFN3S and molecular weight 305.76 g/mol, is a CATO reference standard with documented purity and traceability.

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.
