Purity: ≥98.0% (analytical grade, HPLC); ≥98.5% (pharmaceutical grade); ≥99.0% (high-purity grade, for research use).

Storage Condition: Sealed, stored in a cool and dry place at 2-8℃, protected from light and moisture; keep container tightly closed; avoid high temperature, open flame and contact with oxidizing agents and strong acids; store in an inert atmosphere; for long-term storage, -20℃ freezer is recommended; avoid contact with skin and eyes.

Main Uses

Pharmaceutical & API Field: As a key API and dopamine receptor agonist, it is mainly used for the treatment of idiopathic Parkinson's disease (alleviating signs and symptoms) and moderate-to-severe primary restless legs syndrome (RLS); it can delay the decrease of dopamine content in the brain and improve motor function disorders.
Research & Laboratory Field: Used as a research reagent in molecular biology and pharmacology, mainly for the study of dopamine receptor-related signal pathways, neuropharmacological mechanisms, and the development of related drugs; used as a reference substance for drug analysis and detection.
Pharmaceutical Intermediate Field: Serves as an intermediate for the synthesis of Pramipexole derivatives and related drugs (such as Pramipexole Dihydrochloride, CAS: 104632-25-9), which is widely used in the research and production of antiparkinsonian drugs.
Other Fields: Used in the development and detection of pharmaceutical quality standards; applied in preclinical research of neuropsychiatric diseases, providing support for the research of dopamine-related disorders.
