Applications / Uses (Describe key end-uses clearly):
Pharmaceutical Industry: A crucial purine base and fundamental building block for the synthesis of nucleic acids (DNA & RNA). Used as a key starting material or intermediate in the production of antiviral drugs (e.g., Acyclovir, Ganciclovir derivatives), immunosuppressants, and other nucleoside-based pharmaceuticals. Essential for research in molecular biology and biochemistry.
Food & Nutritional Supplements: Used as a nutrient additive in specialized dietary supplements, infant formulas (where regulations permit), and medical foods. It's a natural component contributing to the overall purine content.
Cosmetics & Personal Care: Functions as a natural pearlescent agent (nacreous pigment) in products like shampoos, soaps, nail polish, and eye makeup due to its light-reflecting crystalline structure (derived from fish scales is traditional, but synthetic is common now). Provides shimmer and shine.
Biochemical Research: Widely used as a reagent and standard in laboratories for genetic research, enzymatic studies, and diagnostic kit development.
Agriculture & Animal Feed: Potential use in specialized feed additives (research grade or where approved)
