Sodium thiosulfate API Introduction
Sodium thiosulfate API appears as colorless crystals or a white crystalline powder CAS: 7772-98-7, Molecular Weight: 158.11. It is readily soluble in water, forming a weakly alkaline solution. As a classic inorganic active pharmaceutical ingredient (API), it possesses chelating and reducing properties. In clinical practice, it is used for the emergency treatment of cyanide poisoning, in dermatological preparations, and for the prevention and treatment of hypersensitivity reactions to contrast agents; additionally, it is widely used in dialysis medications and antidotes.

FAQ
Q1: What is the primary function of Sodium Thiosulfate API?
A1: Sodium Thiosulfate API acts as a reducing agent; it binds with cyanide ions to form non-toxic substances, making it useful for the emergency treatment of cyanide poisoning. It is also used for certain skin conditions and to reduce the risk of allergic reactions to contrast media.
Q2: What are the storage requirements?
A2: Store in a tightly sealed container in a cool, dry place; protect from moisture and efflorescence, and keep away from strong oxidizing agents.
Q3: What are the characteristics of Sodium Thiosulfate regarding formulation?
A3: It is highly soluble in water, making it suitable for injections and topical solutions; however, aqueous solutions are unstable over time, so it is recommended to use them promptly after preparation.
