5-Chloro-3-(pentylsulfanyl)-1,2,4-thiadiazole CAS 89893-30-1

Description

The occurrence of 5-Chloro-3-(pentylsulfanyl)-1,2,4-thiadiazole is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Chloro-3-(pentylsulfanyl)-1,2,4-thiadiazole (CAS 89893-30-1), molecular formula C7H11ClN2S2 and molecular weight 222.76 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Chloro-3-(pentylsulfanyl)-1,2,4-thiadiazole (C7H11ClN2S2) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-3-(pentylsulfanyl)-1,2,4-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.
