Medchemexpress LLC Repaglinide-d5 | 1217709-85-7 | C27H31D5N2O4 | 25 MG
Repaglinide-d5 is a deuterium-labeled variant of Repaglinide. Repaglinide acts as an insulin secretagogue, primarily used in the treatment of type-2 diabetes mellitus. It functions by enhancing the early phase of insulin secretion and increasing the overall amount of insulin released, which helps to reduce postprandial glucose levels.
- Used as a tracer.
- Serves as an internal standard for quantitative analysis using techniques such as NMR, GC-MS, or LC-MS.
