Chemical Structure
Description
The occurrence of 5-Bromo-2-chloro-3-(trifluoromethyl)thiophene is closely related to sulfur-containing functionality, fluorine/chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-2-chloro-3-(trifluoromethyl)thiophene (CAS 2168435-62-7), molecular formula C5HBrClF3S and molecular weight 265.48 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-chloro-3-(trifluoromethyl)thiophene (C5HBrClF3S) contains sulfur-containing functionality, fluorine/chlorine/bromine 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.
