Steroids — a collection of compounds with a cyclopentanoperhydrophenanthrene skeleton, including androstanes, cholanes, cholestanes, estranes, phytosteroids, and pregnanes along with their steroid glycosides, with variations in functional groups and stereochemistry at each ring position. This group serves as structural reference compounds in biochemical research and in the synthesis of steroid derivatives.
Steroids from TCI are used as starting materials for synthesizing hormone derivatives, as analytical standards in chromatography, and as reference compounds in studies of the cholesterol and bile acid biosynthesis pathways. Pharmaceutical and biochemistry researchers use them for developing detection methods, structural modification, and structure-activity relationship studies in academic and industrial laboratories.
Example products in this collection: TCI U0102 126784-99-4 Ulipristal Acetate, TCI B6325 471-95-4 Bufotalin, TCI U0030 128-13-2 Ursodeoxycholic Acid, TCI C0315 83-44-3 Deoxycholic Acid, TCI T4049 13647-35-3 Trilostane, TCI C0316 302-95-4 Sodium Deoxycholate, TCI T3736 20183-47-5 Tenuifolin, TCI C0317 80-97-7 beta-Cholestanol (contains alpha-Cholestanol).
Selection should consider purity, stereochemical configuration (alpha/beta), and the presence of isomer mixtures, such as beta-Cholestanol, which contains a small amount of alpha-Cholestanol. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
