Chemical Structure
Description
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.
1,1,1-trifluoro-3-(thiophen-3-yl)propan-2-one (CAS 125774-46-1) is a high-purity analytical reference standard with the molecular formula C7H5F3OS and a molecular weight of 194.17 g/mol.
1,1,1-trifluoro-3-(thiophen-3-yl)propan-2-one (C7H5F3OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
