The core mechanism of PMS powder relies on non-enzymatic, reversible electron transfer, serving as a critical intermediate that bridges dehydrogenase systems with chromogenic substrates and electron acceptors; it operates entirely through regulatory mechanisms in *in vitro* biochemical reactions and possesses no *in vivo* pharmacological therapeutic activity. In liquid-phase biochemical systems, PMS undergoes rapid, non-enzymatic reduction by reduced coenzymes such as NADH and NADPH to form a stable semiquinone reduction product. This product, characterized by high electron-donating activity, rapidly transfers electrons to terminal acceptors-such as oxygen, cytochrome c, or tetrazolium salts-while simultaneously undergoing oxidative regeneration to complete a cyclic electron transfer pathway. Unlike enzymatic reactions, PMS-mediated electron transfer requires no biological enzyme catalysis; it offers stable and highly controllable reaction rates alongside excellent redox reversibility, thereby maintaining the electron balance of the biochemical system. This capability provides precise technical support for applications such as enzyme activity assays and the construction of oxidative stress models, constituting the fundamental technical principle behind its suitability for a wide range of *in vitro* biochemical experiments.

Leveraging its stable electron-mediating properties, PMS powder is primarily utilized in *in vitro* biochemical research and industrial biochemical testing, with its core applications falling into three main categories. First, it is used to construct enzyme activity assay systems-often in conjunction with ascorbic acid and tetrazolium salts-for the quantitative determination of various dehydrogenases, such as succinate dehydrogenase, lactate dehydrogenase, and nitric oxide reductase; it serves as a key mediator in chromogenic systems for enzymology experiments. Second, it is employed in histochemical analysis, acting as a mediator component for Complex II to facilitate the setup of experimental models related to the cellular respiratory chain and the study of cellular oxidative metabolic mechanisms. Third, it is used in the development of biosensors and oxidative stress models; it can controllably induce the generation of superoxide radicals, supporting research into erythrocyte deformability and *in vitro* oxidative stress systems, while also aiding in the optimization of electron transfer pathways for biochemical sensors. Additionally, the product is suitable for clinical *in vitro* biochemical tests, such as micro-colorimetric assays for blood ethanol, serving as a core raw material for *in vitro* diagnostic reagents.

Currently, the electron transfer mediators commonly used in the biochemical field include 1-methoxy-5-methylphenazinium methyl sulfate (MPMS) and various artificial electron carriers; technical distinctions among them center on stability, compatibility, and application scenarios. Compared to MPMS, PMS is positioned for general-purpose biochemical assays, offering superior water solubility, controllable costs, and a mature production process, making it suitable for routine enzymatic assays and basic research. In contrast, MPMS-modified with a methoxy group-exhibits enhanced photochemical stability, making it better suited for high-precision biosensing and long-term *in vitro* experiments, though it entails complex synthesis, higher costs, and more limited versatility. Compared to traditional artificial electron carriers, PMS offers key advantages such as high non-enzymatic reaction efficiency, minimal side reactions, and low system interference; its redox reversibility far surpasses that of standard carriers, significantly enhancing the accuracy and reproducibility of biochemical assays. Overall, PMS has become the preferred medium for general *in vitro* biochemical testing due to its comprehensive technical profile-characterized by high stability, high compatibility, mature production technology, and excellent cost-effectiveness-while its modified derivatives target specialized, high-precision research applications.

Risks are primarily associated with physicochemical exposure and experimental handling, representing technical safety concerns at the reagent-usage level. First, the powder is mildly irritating; contact with the eyes, respiratory tract, or mucous membranes may cause mild irritation. Therefore, protective equipment must be worn throughout handling to prevent exposure to airborne dust. Second, PMS can mediate the generation of free radicals; Second, PMS can mediate the generation of free radicals, and high concentrations can accelerate oxidative damage to in vitro biological samples, interfering with the accuracy of experimental data. Therefore, it is necessary to strictly follow the experimental standard concentration ratio. prolonged exposure to light or high temperatures can trigger oxidative degradation, leading to a decline in electron-transfer activity and experimental errors. Consequently, it must be stored in a sealed container, protected from light, and kept at low temperatures. Furthermore, aqueous PMS solutions should not be stored for extended periods; they must be used promptly after preparation to prevent ingredient degradation or impurity precipitation, which could destabilize the experimental system. As a legitimate, compliant product, it poses no risk of unknown toxicity; provided that standardized operating and storage protocols are followed, all usage-related hazards can be effectively avoided.
