Safinamide Mesylate, also labeled as EMD 1195686, NW 1015 and PNU-151774E, has CAS No. 202825-46-5, molecular formula C17H19FN2O2·CH4O3S and molecular weight of 398.45. It is a white to tan chiral powder with a decomposing melting point of 210°C and specific optical rotation of [α]D25 +12.9° (c=1.1, 98% acetic acid). This compound is highly water-soluble at ≥15 mg/mL and requires cold storage at 2–8°C for stability. As a selective monoamine oxidase B inhibitor for Parkinson’s disease research, we supply high-purity reagent-grade Safinamide Mesylate, along with its synthetic intermediates, reference standards and related impurities. Complete technical documents including chiral characterization data, MSDS, synthetic procedures and pharmacological research materials are provided, supporting laboratory chiral analysis, neurological drug screening and pharmaceutical development for Parkinson’s treatment.
