Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 249.72 g/mol gives 2-((2-Chlorophenyl)thio)nicotinaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-((2-Chlorophenyl)thio)nicotinaldehyde (CAS 338982-32-4), molecular formula C12H8ClNOS and molecular weight 249.72 g/mol, is a CATO reference standard with documented purity and traceability.
2-((2-Chlorophenyl)thio)nicotinaldehyde (C12H8ClNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
