Collection: Vitamins [Vitamins and Related Compounds]

Vitamins [Vitamins and Related Compounds] — includes vitamins and related compounds such as cholecalciferol, L-ascorbic acid and its sodium salt, vitamin K4, and tocopherols in free form and as acetates. This group represents compounds with diverse functional groups, from steroid structures to chromanols and naphthoquinones.

Compounds in this category are used by biochemistry and food science researchers as analytical standards for determining vitamin content, as well as research materials for stability and formulation studies. D-alpha-tocopherol and its acetate form are often studied in lipid-based antioxidant research, while L-ascorbic acid and its sodium salt are used as reducing agents or standards in various analytical chemistry tests.

Example products in this collection: TCI C0314 67-97-0 Cholecalciferol, TCI C0005 50-14-6 Calciferol, TCI A0537 50-81-7 L-Ascorbic Acid, TCI C0449 68-19-9 Vitamin B12, TCI A0539 134-03-2 Sodium L-Ascorbate, TCI C0560 7235-40-7 beta-Carotene, TCI V0103 573-20-6 Vitamin K4, TCI D5526 54573-75-0 Doxercalciferol.

Distinguish the free form from the acetate or sodium salt forms, as they differ in solubility and stability against oxidation, and pay attention to stereochemical configuration such as D-alpha, which is relevant for certain research purposes. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
