3-((2,4-Dichlorobenzyl)thio)-N-methylthiophene-2-carboxamide (CAS 303151-44-2), molecular formula C13H11Cl2NOS2 and molecular weight 332.27 g/mol, is a CATO reference standard with documented purity and traceability.
3-((2,4-Dichlorobenzyl)thio)-N-methylthiophene-2-carboxamide (C13H11Cl2NOS2) 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.
