Menadione bisulfite API Manufacturers & Suppliers

Menadione bisulfite (CAS Number 130-36-9) is a synthetic chemical compound related to the vitamin K family, classified structurally as a naphthoquinone and functioning within the broader category of fat-soluble vitamins. While not explicitly approved for therapeutic use, it is categorized under experimental agents and is recognized for its role as a micronutrient and coagulant.

Clinically, menadione analogs are associated with modulation of hemostasis due to their involvement in the vitamin K cycle, which is essential for the post-translational gamma-carboxylation of specific clotting factors, including prothrombin and factors VII, IX, and X. This activity underpins their categorization as antifibrinolytic agents and fibrin modulating agents, potentially influencing blood coagulation pathways. However, menadione bisulfite itself lacks specified clinical indications and pharmacodynamic data within current regulatory frameworks.

The mechanism of action, inferred from its vitamin K class, involves serving as an essential cofactor for the enzyme gamma-glutamyl carboxylase, facilitating the activation of vitamin K-dependent proteins that regulate coagulation and bone metabolism. This biochemical pathway is crucial in maintaining hemostatic balance.

Key ADME parameters for menadione bisulfite are not extensively characterized in the literature; generally, vitamin K analogues exhibit variable oral bioavailability, hepatic metabolism, and biliary excretion. Menadione derivatives may undergo rapid conversion to active vitamin K forms or be eliminated depending on their formulation and route of administration.

Safety considerations note that menadione compounds, particularly synthetic forms, have been associated with potential toxicity at high doses, including hemolytic anemia and liver toxicity, warranting cautious use. Its safety profile necessitates thorough evaluation when considered for clinical or nutritional use, distinct from natural vitamin K1 and K2 isoforms.

Currently, menadione bisulfite is primarily of interest in research and experimental contexts rather than established therapeutic applications. Notable reference products are limited, and its utility is generally confined to supplemented nutritional formulations or investigational studies.

For API procurement, sourcing menadione bisulfite requires stringent quality control due to its chemical reactivity and potential toxicity. Manufacturers should ensure compliance with pharmacopeial standards and regulatory requirements for purity, residual solvents, and impurity profiles. Stability and handling considerations are critical to maintain compound integrity during storage and supply chain logistics.
