Collection: Building Blocks for Pharmaceutical Ingredients (for Research and Experimental Use)

Building Blocks for Pharmaceutical Ingredients (for Research and Experimental Use) — compiles small molecular building blocks such as amine derivatives, halogenated oxetanes, azetidinones, and heterocyclic fragments used as starting materials for synthesizing drug candidates in research and experimental use. These building blocks serve as synthetic entry points for assembling complex molecular structures in the development of active pharmaceutical ingredients.

These building blocks are used by process chemists and medicinal chemists to build drug candidates through ring-forming reactions, nucleophilic substitution, or protection-deprotection of functional groups in the early stages of synthesis research. Fragments such as brominated oxetanes and protected azetidinones function as scaffolds to expand structural diversity in structure-activity relationship studies and route optimization at research scale.

Example products in this collection: TCI A0295 107-35-7 2-Aminoethanesulfonic Acid, TCI B5641 2402-83-7 3,3-Bis(bromomethyl)oxetane, TCI A0303 60-19-5 Tyramine Hydrochloride, TCI B5682 877399-00-3 (R)-5-Bromo-3-[1-(2,6-dichloro-3-fluorophenyl)ethoxy]pyridin-2-amine, TCI A0067 2623-33-8 4'-Acetoxyacetanilide, TCI B5687 68014-21-1 tert-Butyl (Triphenylphosphoranylidene)carbamate, TCI V0193 2182-14-1 Vindoline, TCI B5715 149198-47-0 tert-Butyl (3R,4S)-2-Oxo-4-phenyl-3-[(triethylsilyl)oxy]azetidine-1-carboxylate.

Pay attention to purity, stereochemical configuration at chiral centers, optical isomer purity, and the type of protecting group attached, so that they match the synthesis route and the next reaction step. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
