CAS 21645-51-2: Aluminum hydroxide

Description:Aluminum hydroxide, with the CAS number 21645-51-2, is an inorganic compound with the formula Al(OH)₃. It typically appears as a white, amorphous powder or as a crystalline solid. This compound is amphoteric, meaning it can react with both acids and bases, which allows it to neutralize acidic environments. Aluminum hydroxide is commonly used as an antacid in medicine to relieve symptoms of heartburn and indigestion, as it can neutralize stomach acid. Additionally, it serves as a flocculating agent in water purification processes and is utilized in the production of aluminum salts. The compound is insoluble in water but can dissolve in strong acids or bases, forming aluminum salts. Its low solubility contributes to its effectiveness in various applications, including as a filler in pharmaceuticals and cosmetics. Safety considerations include its potential to cause gastrointestinal disturbances when ingested in large amounts, and it should be handled with care in industrial settings to avoid inhalation of dust.
