Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2-Chlorophenyl)-2-(4-methoxybenzenesulfinyl)acetamide.
CATO supplies N-(2-Chlorophenyl)-2-(4-methoxybenzenesulfinyl)acetamide (CAS 339097-99-3), a certified reference material (molecular formula C15H14ClNO3S, MW 323.79 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H14ClNO3S, N-(2-Chlorophenyl)-2-(4-methoxybenzenesulfinyl)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 323.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
