Description

Cysteamine CAS NO 60-23-1 is a versatile organosulfur compound featuring a simple structure with both an amine and a thiol functional group. This bifunctional nature makes it a critical building block and active agent in pharmaceutical synthesis and biochemical research. It is essential for manufacturers and R&D teams in the pharmaceutical, biotechnology, and specialty chemical sectors.

Application

• Pharmaceutical Intermediate: Key raw material for synthesizing drugs like cysteamine bitartrate, used to treat cystinosis and nephropathic cystinosis.
• Radiation Protectant & Detoxifying Agent: Used in research and formulations for its ability to protect against radiation damage and act as a detoxifying agent.
• Biochemical Research: Employed as a reducing agent for disulfide bonds in proteins and peptides, and as a precursor for coenzyme A synthesis.
• Cosmetic & Personal Care: Acts as an active ingredient in hair care formulations, particularly in permanent wave solutions and depilatory agents.
• Animal Feed Additive: Utilized to reduce the cysteine content in feed, which can help prevent certain metabolic disorders in livestock.
• Polymer & Resin Modification: Serves as a chain transfer agent or cross-linking agent in the production of specialty polymers and resins.

Quality Control

Our Cysteamine is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the required specifications for pharmaceutical and industrial applications. Certificates of Analysis (COA) are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. Keep away from strong oxidizing agents.
