Chemical Overview
Sodium Formaldehyde Sulphoxylate (SFS), also known as Rongalite (CAS 149-44-0/6035-47-8), is a water-soluble white crystalline powder. As a powerful reducing agent, it releases formaldehyde and sulfoxylate ions under controlled conditions, making it essential in textile bleaching, polymer synthesis, and dye stripping.
