Chemical Structure
Description
The occurrence of 2-[(3-Chlorophenyl)sulfanyl]-6-(4-fluorophenyl)pyridine-3-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-[(3-Chlorophenyl)sulfanyl]-6-(4-fluorophenyl)pyridine-3-carbonitrile (CAS 252059-86-2) is a high-purity analytical reference standard with the molecular formula C18H10ClFN2S and a molecular weight of 340.80 g/mol.
2-[(3-Chlorophenyl)sulfanyl]-6-(4-fluorophenyl)pyridine-3-carbonitrile (C18H10ClFN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
