Chemical Structure
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-acetylphenyl)-2,4,5-trichlorobenzenesulfonamide.
CATO supplies N-(2-acetylphenyl)-2,4,5-trichlorobenzenesulfonamide (CAS 303152-67-2), a certified reference material (molecular formula C14H10Cl3NO3S, MW 378.66 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H10Cl3NO3S, N-(2-acetylphenyl)-2,4,5-trichlorobenzenesulfonamide 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 378.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
