Description

Compared with other compounds in its class, the molecular weight of 245.13 g/mol gives 5-Chloro-3-[(4-chlorophenyl)methyl]-1,2,4-thiadiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Chloro-3-[(4-chlorophenyl)methyl]-1,2,4-thiadiazole (CAS 90418-16-9), molecular formula C9H6Cl2N2S and molecular weight 245.13 g/mol, is a CATO reference standard with documented purity and traceability.

5-Chloro-3-[(4-chlorophenyl)methyl]-1,2,4-thiadiazole (C9H6Cl2N2S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
