Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-N-(3-cyano-4-(methylsulfonyl)phenyl)benzamide.
4-Chloro-N-(3-cyano-4-(methylsulfonyl)phenyl)benzamide (CAS 320421-54-3) is a high-purity analytical reference standard with the molecular formula C15H11ClN2O3S and a molecular weight of 334.78 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-N-(3-cyano-4-(methylsulfonyl)phenyl)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
