Polyamines [Bioactive Small Molecules] — gathers aliphatic polyamine compounds with repeating chains of primary and secondary amine groups, including agmatine, spermidine, and multi-stage ethylenediamine derivatives, which function as basic nitrogen units in cellular biochemistry and in the synthesis of polyamine derivative molecules.
Polyamines in this category are widely used by biochemistry and molecular biology researchers as reagents for studying polyamine metabolism, as precursors for synthesizing bioactive derivatives, and as components in preparing polyamine chelators or ligands for cell research. Derivatives such as sulfate or hydrochloride salts are often chosen for their storage stability and ease of dissolution in aqueous media for laboratory testing.
Example products in this collection: TCI A0310 2482-00-0 Agmatine Sulfate, TCI D0081 333-93-7 1,4-Diaminobutane Dihydrochloride, TCI X0080 89690-11-9 Xylemin Dihydrochloride, TCI D0090 56-18-8 3,3'-Diaminodipropylamine, TCI T1212 4961-40-4 Triethylenetetramine Tetrahydrochloride, TCI D0099 1476-39-7 1,5-Diaminopentane Dihydrochloride, TCI B1952 10563-26-5 N,N'-Bis(3-aminopropyl)ethylenediamine, TCI D0108 462-94-2 1,5-Diaminopentane.
Pay attention to the salt form (sulfate, hydrochloride, or free base), purity level, and the number of amine groups in the chain, as these affect solubility and reactivity of the compounds in biochemical experiments. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
