In the field of biomedicine, the stability and safety of drugs have always been the core issues in research and production.Nanjing Chemical Reagent Co., LtdNanjing Reagent, with 67 years of technological accumulation, has launchedMedicinal excipients for injection of gentian acidWith its antioxidant properties and strict quality standards, it has become the "invisible cornerstone" of injection formulations such as nuclear drugs and biologics.

Packaging: Low density polyethylene bag, 5g/bag (note: packaging specifications can be added according to market demand without changing the inner packaging material)
gentianic acid(2,5-dihydroxybenzoic acid) as a polyhydroxycarboxylic acid, its unique molecular structure endows it with strong antioxidant capacity. The two hydroxyl (- OH) groups on the para position of its benzene ring make its free radical scavenging efficiency significantly higher than that of monohydroxyphenolic acid substances. In the application of injections, gentian acid can effectively protect the active ingredients of drugs from degradation by capturing free radicals and inhibiting oxidation reactions, thereby prolonging the drug's shelf life and reducing the risk of adverse reactions. For example, in nuclear drug formulations such as lutetium oxooctreotide injection and gallium [68Ga] dotteride injection, trace addition (below 1mg/mL) can significantly improve product stability.
More noteworthy is that gentian acid has a synergistic effect with antioxidants such as vitamin C, which can further strengthen the antioxidant system of the formulation and provide more flexible solutions for complex formulas.
Nanjing reagentNot only does it provide standardized gentian acid products, but it also meets customers' personalized needs through a "multi variety flexible fast response" service ecosystem, continuously deepens independent product research and development, and strives to overcome the bottleneck of import substitution.
