D-Trp(23)-Teriparatide는 테리파라타이드의 서열 변이형 펩타이드 불순물로, 말단 L-트립토판 잔기가 D-엔안티오머로 치환된 입체이성질체 유사체이며 절단 산물이 아니다. 이러한 에피머성 불순물은 고상 펩타이드 합성, 탈보호 단계 또는 스트레스 저장 조건에서의 라세미화로 발생할 수 있다. 분자식과 분자량이 제시되지 않았으므로 구조 규명은 직교적 특성분석에 의존한다. 민감한 정량에는 일반적으로 키랄 또는 고해상도 분리를 갖춘 LC-MS/MS가 필요하며, 펩타이드 매핑과 필요 시 이온 이동도 또는 NMR을 통해 입체배열 반전을 확인한다.
