N-Isopropyl-2-(3-(4-oxo-4,4a-dihydroquinazolin-2-yl)phenoxy)acetamide (CAS 2121561-39-3), also described as Acetamide, 2-[3-(3,4-dihydro-4-oxo-2-quinazolinyl)phenoxy]-N-(1-methylethyl), is an identifiable process-related impurity characterized by a quinazolinone core linked to a phenoxy acetamide side chain with an N-isopropyl substituent. Its presence typically arises from incomplete cyclization, O-alkylation side reactions or partial acylation during synthesis and can affect assay, purity and stability profiles. Analytical control is achieved using reversed-phase HPLC coupled with LC-MS and confirmed by NMR and HRMS. Control strategies include optimized reaction conditions, targeted purification, specification limits consistent with ICH impurity guidance and forced-degradation studies to define degradant pathways.見積もり依頼
