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 Ethyl(4-fluoro-2-methylphenyl)sulfane.
Ethyl(4-fluoro-2-methylphenyl)sulfane (CAS 1314976-97-0), molecular formula C9H11FS and molecular weight 170.25 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl(4-fluoro-2-methylphenyl)sulfane (C9H11FS) contains 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. 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.
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.
