Description

Vitamin K5 is a synthetic naphthoquinone derivative, distinct from the naturally occurring K1 and K2 vitamins, with the specific identifier CAS NO 83-70-5. This compound is valued for its potent antimicrobial and preservative properties, offering a critical solution for extending shelf life and preventing spoilage in sensitive applications. It is primarily sought by manufacturers in the animal feed, food preservation, and pharmaceutical intermediate sectors where microbial control is paramount.

Application

• Animal Feed Additive: Used as a preservative and antimicrobial agent in feed to prevent mold growth and nutrient degradation.
• Food Preservation: Employed as an antimicrobial agent for certain food products to inhibit bacterial and fungal growth.
• Pharmaceutical Intermediate: Serves as a key synthetic precursor in the production of other vitamin K analogs and specific active pharmaceutical ingredients (APIs).
• Research & Development: Utilized in biochemical and microbiological studies investigating quinone chemistry and antimicrobial mechanisms.
• Industrial Biocide: Applied in select industrial processes or material preservation where microbial inhibition is required.
