Zinc pyroglutamate, also known as Zinc PCA, is a zinc amino acid chelate used primarily in dietary supplements and skincare products for its bioavailability and antioxidant properties. It supports immune function, skin health, and wound healing while offering gentle absorption compared to inorganic zinc salts. This chemical has a CAS number of 15454-75-8, a molecular formula of C10H10N2O6Zn, and a molecular weight of 321.6 g/mol. It is stored at ambient conditions but requires careful handling due to its Danger classification.
