Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system, 2-Methyl-5-(1H-1,2,4-triazol-5-yl)-4-(trifluoromethyl)thiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-Methyl-5-(1H-1,2,4-triazol-5-yl)-4-(trifluoromethyl)thiazole (CAS 338978-10-2), molecular formula C7H5F3N4S and molecular weight 234.20 g/mol, is a CATO reference standard with documented purity and traceability.
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.
