Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2-Ethoxy-3,5-difluorophenyl)(methyl)sulfane (CAS 1379358-59-4) is a high-purity analytical reference standard with the molecular formula C9H10F2OS and a molecular weight of 204.24 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (2-Ethoxy-3,5-difluorophenyl)(methyl)sulfane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
