Menadione
Description
Menadione (CAS 58-27-5), commonly known as Vitamin K3, is a synthetic naphthalene-based compound used as a precursor and active ingredient across pharmaceutical and industrial manufacturing.
It functions as an antioxidant stabilizer and catalytic intermediate in formulations where controlled oxidation activity is required. In pharmaceutical manufacturing, it serves as a starting material for producing Vitamin K analogues.
These analogues are used in injectable and oral dosage forms. Cosmetic formulators incorporate it into antioxidant-active preparations targeting skin conditioning and stability enhancement in various topical applications.
In textile and paper processing, it functions as a catalytic agent in dye fixation and oxidative finishing processes. Leather treatment operations also utilize it as a processing aid where controlled redox activity supports outcomes.
Menadione is supplied as a yellow crystalline powder, which is the standard physical form across commercial grades. Pharmaceutical-grade material is available to USP and BP specifications for regulated environments.
Technical-grade product is offered for industrial applications in textile, paper, and leather processing where compendial certification is not required. This ensures versatility across multiple manufacturing sectors and chemical processes.
