Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Difluoromethyl)-2-(trifluoromethyl)thiazole.
4-(Difluoromethyl)-2-(trifluoromethyl)thiazole (CAS 1864985-41-0), molecular formula C5H2F5NS and molecular weight 203.13 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Difluoromethyl)-2-(trifluoromethyl)thiazole (C5H2F5NS) contains a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
