Chemical Structure
Description
2-Iodo-5-(trifluoromethyl)benzo[d]thiazole (CAS 1188077-83-9), molecular formula C8H3F3INS and molecular weight 329.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Iodo-5-(trifluoromethyl)benzo[d]thiazole (C8H3F3INS) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
