설명
Nilotinib EP Impurity B, 즉 Nilotinib Related Compound B는 CAS 18595-18-1, 분자식 C9H11NO2, 분자량 165.19 g/mol의 저분자 방향족 아미노알코올에 해당한다. 그 구조는 니트로사민 계열 불순물이 아니라, 치환된 벤질아민 골격 형성과 연관된 합성 중간체 또는 공정 유래 부산물과 부합한다. 평가는 일반적으로 LC-MS/MS, 고분해능 MS, NMR에 의한 상호보완적 동정이 필요하며, 휘발성이 확보될 경우 유도체화 후 GC-MS도 활용된다. 규제 관점에서 이 성분은 impurity profiling 체계에서 지정된 관련물질로 관리된다.
