description Product Description
Trichloroacetic acid (TCA) is widely used in dermatology for chemical peels to treat skin conditions such as acne, scars, and hyperpigmentation. It works by exfoliating the outer layers of the skin, promoting the growth of new, healthier skin cells. In pathology, TCA is employed as a protein precipitant to isolate and analyze proteins in laboratory settings. It is also used in the treatment of warts, where it acts as a caustic agent to destroy wart tissue. Additionally, TCA finds application in biochemistry for fixing gels in electrophoresis, aiding in the separation and study of nucleic acids and proteins. Its strong acidic properties make it useful in various industrial processes, including the synthesis of organic compounds.
