2-Iodo-5-(trifluoromethyl)-1,3,4-thiadiazole CAS 1393843-44-1

Description

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

2-Iodo-5-(trifluoromethyl)-1,3,4-thiadiazole (CAS 1393843-44-1), molecular formula C3F3IN2S and molecular weight 280.01 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Iodo-5-(trifluoromethyl)-1,3,4-thiadiazole (C3F3IN2S) is characterized by a nitrile group, sulfur-containing functionality, fluorine/iodine 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.

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.
