Collection: Vitamins and Related Compounds

Vitamins and Related Compounds — gathers vitamins and compounds related to their structures, including fat-soluble and water-soluble derivatives such as calciferol, ascorbate, and carnitine, which serve as cofactors as well as model molecules in biochemical studies. This category also includes synthetic analogs and derivatives used as reference compounds in nutrition and metabolism research.

Vitamins and Related Compounds are used by biochemistry and molecular biology researchers as analytical standards for quantifying vitamin content in food or biological samples, and as in vitro test materials in studies of metabolic pathways and oxidative stress. Compounds such as ascorbic acid and choline are also used as antioxidant additives or precursors in organic synthesis and laboratory research formulations.

Example products in this collection: TCI C0314 67-97-0 Cholecalciferol, TCI C0005 50-14-6 Calciferol, TCI I0848 58186-27-9 Idebenone, TCI C0049 541-15-1 L-Carnitine, TCI A0520 89-65-6 D-Araboascorbic Acid, TCI C0050 461-05-2 DL-Carnitine Hydrochloride, TCI A0537 50-81-7 L-Ascorbic Acid, TCI C0326 123-41-1 Choline (47-50% in Water) (stabilized with Hydrazine Monohydrate).

Compound selection should consider stereochemical forms such as D or L isomers, purity levels, and stability against light and oxidation, which are common in the vitamin group, including the need for additional stabilizers in certain solutions. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
