2-Propenoic acid, 3-(4-chlorophenyl)-2-cyano- 69727-07-7 Cinnamic acid, p-chloro-.alpha.-cyano- NSC-2479 NSC2479 (CAS 69727-07-7) is a high-purity analytical reference standard with the molecular formula C10H12ClNO2 and a molecular weight of 213.66 g/mol.
Based on its molecular formula C10H12ClNO2, 2-Propenoic acid, 3-(4-chlorophenyl)-2-cyano- 69727-07-7 Cinnamic acid, p-chloro-.alpha.-cyano- NSC-2479 NSC2479 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 213.66 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.
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.
