Chemical Structure
Description
5-Fluoro-2-mercapto-3-(trifluoromethyl)pyridine (CAS 1214385-35-9) is a high-purity analytical reference standard with the molecular formula C6H3F4NS and a molecular weight of 197.15 g/mol.
5-Fluoro-2-mercapto-3-(trifluoromethyl)pyridine (C6H3F4NS) contains a nitrile group, sulfur-containing functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
