Vitamin K1-d7

Vitamin K1-d7 (CAS No.: 1373049-34-3) is the stable isotope-labeled analog of Vitamin K1, with 7 deuterium atoms introduced into its molecular structure. It is mainly used as an internal standard in biomedical research to improve the accuracy and sensitivity of liquid chromatography–tandem mass spectrometry (LC-MS/MS) analysis. In metabolism studies, Vitamin K1-d7 can be used to trace the metabolic pathways and kinetic processes of Vitamin K1 in vivo, helping researchers gain deeper insight into its roles in biological processes such as blood coagulation, bone metabolism, and cell signaling. Owing to its stable isotope-labeling properties, Vitamin K1-d7 shows good stability and reproducibility in both in vitro and in vivo experiments, and is commonly used in drug screening and metabolism research. The dose or concentration used in experiments typically depends on the experimental design and research objectives.
