Alkaloids — cover natural nitrogen-containing cyclic compounds from various frameworks such as imidazole, indole, isoquinoline, piperidine, purine, pyridine, quinoline, and tropane, compiled to represent the structural diversity of alkaloids. This group presents variations of heterocyclic ring frameworks that are characteristic of plant secondary metabolites.
These alkaloids are used by natural product chemists and biochemists as reference compounds for research on biosynthetic pathways, analytical standards in chromatography, or test materials for in vitro studies of molecular interactions. Examples such as tyramine and cinchonidine are often used as structural comparators in developing methods for isolating and identifying alkaloids from natural sources.
Product examples in this collection: TCI A0302 51-67-2 Tyramine, TCI B6485 149-64-4 Buscopan, TCI A0303 60-19-5 Tyramine Hydrochloride, TCI C0001 561-20-6 Cacotheline Monohydrate, TCI A0305 62-31-7 3-Hydroxytyramine Hydrochloride, TCI C0293 85-18-7 8-Chlorotheophylline, TCI A0523 300-08-3 Arecoline Hydrobromide, TCI C0347 485-71-2 Cinchonidine.
Pay attention to the salt form (hydrochloride, hydrobromide) or free base, the purity level, and the presence or absence of crystal hydrate, which affect molecular weight calculations. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
