5-Chloro-4-(2,4-dichlorophenyl)-1,2,3-thiadiazole CAS 338407-85-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-4-(2,4-dichlorophenyl)-1,2,3-thiadiazole.

5-Chloro-4-(2,4-dichlorophenyl)-1,2,3-thiadiazole (CAS 338407-85-5) is a high-purity analytical reference standard with the molecular formula C8H3Cl3N2S and a molecular weight of 265.55 g/mol.

Based on its molecular formula C8H3Cl3N2S, 5-Chloro-4-(2,4-dichlorophenyl)-1,2,3-thiadiazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 265.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 5-Chloro-4-(2,4-dichlorophenyl)-1,2,3-thiadiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
