3-(Trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine hydrochloride (CAS 762240-92-6)

Application and positioning

The bicyclic triazolopiperazine of sitagliptin, as the hydrochloride and already carrying the trifluoromethyl group. The salt form matters here: the free base is hygroscopic, while the hydrochloride crystallises cleanly. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots; process and regulatory documentation is coordinated case by case with the manufacturing site.

Quality and documentation
