Description

Guanosine 5'-Phosphate Disodium Salt Hydrate is a high-purity nucleotide salt widely used as a critical biochemical building block and flavor enhancer. This compound is essential for research and industrial processes requiring a defined source of guanosine monophosphate (GMP). It serves key roles in the pharmaceutical, biotechnology, and food ingredient sectors, where precise molecular structure and consistent quality are paramount for successful outcomes.

Application

• Pharmaceutical & Biotechnology Research: As a precursor in nucleic acid synthesis, enzyme studies, and cell culture media formulation.
• Food & Beverage Industry: Utilized as a flavor enhancer (disodium 5'-guanylate, E627) in savory products, soups, sauces, and snack foods.
• Diagnostic Reagent Manufacturing: A key component in the production of diagnostic kits and biochemical assays.
• Biochemical Synthesis: Serves as a starting material or intermediate for the synthesis of more complex nucleotides, nucleoside analogs, and pharmaceutical actives.
• Cell Signaling Studies: Used in research focused on intracellular signaling pathways where GMP acts as a secondary messenger.
• Cosmetic & Personal Care: Incorporated into advanced skincare formulations for its potential bioactive properties.
