Description

Cysteamine Bitartrate is the bitartrate salt of cysteamine, a stable and pharmaceutically relevant form of the aminothiol compound. This product is essential for its role as a key intermediate and active pharmaceutical ingredient (API) in the synthesis of life-saving medications and critical research. It is primarily required by pharmaceutical manufacturers, biotechnology research facilities, and fine chemical synthesis units focused on metabolic and ophthalmic disorders.

Application

• Pharmaceutical API: Primary use as the active ingredient in medications for cystinosis, a rare metabolic disorder.
• Ophthalmic Solutions: Formulation component in eye drops for corneal cystine crystal dissolution.
• Biochemical Research: Critical reagent in studies involving thiol metabolism, oxidative stress, and radioprotection.
• Precursor Synthesis: Key intermediate in the manufacture of more complex thiol-based pharmaceutical compounds.
• Cosmetic & Dermatology: Investigational use in depigmenting agents and formulations for skin conditioning.
• Veterinary Medicine: Potential application in veterinary pharmaceuticals for similar metabolic conditions.

Quality Control

Our Cysteamine Bitartrate is manufactured under strict quality systems suitable for pharmaceutical applications. Each batch is tested to meet high-purity standards, with specifications aligning with current industry and pharmacopeial expectations for API-grade materials. A comprehensive Certificate of Analysis (COA) documenting identity, purity, and related substances is provided with every shipment to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. For long-term storage, consider using desiccants and maintaining an inert atmosphere to minimize oxidation.
