Used as a reagent in analytical chemistry for spectrophotometric determination, particularly for the detection of fluoride ions and other analytes, due to its ability to form colored complexes. In medicine, it serves as an antacid and protective agent for treating gastrointestinal disorders, forming a protective coating over ulcers and irritated tissues in the stomach and intestines to promote healing. It also exhibits mild antimicrobial properties, reducing infection risk in gastric lesions, and is found in formulations for diarrhea and gastritis. Topically in dermatology, it treats minor wounds and skin irritations with its soothing and astringent effects. Additionally, it is used in certain dental preparations for managing canker sores and oral mucosal injuries.
