Description

5'-Guanylic Acid, Dipotassium Salt is a high-purity nucleotide salt, a key building block in biochemical research and industrial applications. Its primary value lies in its role as a flavor enhancer (disodium 5'-guanylate precursor) and as a critical reagent in molecular biology and pharmaceutical synthesis. This product is essential for manufacturers and research institutions in the food & beverage, nutraceutical, and life science sectors seeking reliable, high-quality nucleotide derivatives.

Application

• Flavor Enhancer & Food Additive: As a precursor for the production of disodium 5'-guanylate (E627), a potent umami flavor enhancer used in savory foods, snacks, and seasonings.
• Pharmaceutical Intermediate: Used in the synthesis of antiviral and anticancer nucleoside analogs, as well as in the production of specialized nucleotide-based active pharmaceutical ingredients (APIs).
• Biochemical Research & Diagnostics: Serves as a substrate, standard, or building block in enzymatic studies, PCR reagent preparation, and various molecular biology assays.
• Nutraceutical & Dietary Supplements: Incorporated into formulations for specialized nutritional products targeting cellular energy metabolism and health.
• Cell Culture Media Component: Used as a defined component in specialized cell culture media for biotechnology and vaccine production.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
