  • Applications

    Vitamin K, CAS 12001-79-5, is used as a nutritional ingredient in dietary supplements and pharmaceutical formulations; it may also be employed for food fortification where permitted by regulations to maintain vitamin K levels. It serves as a feed additive in animal nutrition to support vitamin K requirements in livestock. In cosmetics and personal care, it is used in select formulations as an active ingredient aimed at skin and nail care. In analytical and quality-control settings, vitamin K is used as a reference standard for assay development and product testing.
