1-(5-carboxypentyl)-2,3,3-trimethylindol-1-ium-5-sulfonate CAS:146368-08-3 is a small molecule linker that contains a carboxylic acid, a sulfonate group, and a quaternary ammonium group. Small molecule linkers are used in bioconjugation and drug delivery to covalently attach two or more molecules together, or to attach a small molecule drug to a targeting moiety, such as an antibody or a nanoparticle.
In the case of 1-(5-carboxypentyl)-2,3,3-trimethylindol-1-ium-5-sulfonate, the carboxylic acid and sulfonate groups can be used to react with amine or thiol groups on other molecules, forming stable covalent linkages. The quaternary ammonium group can also confer water solubility to the molecule, allowing it to be easily incorporated into aqueous environments, such as in biological systems.
1-(5-carboxypentyl)-2,3,3-trimethylindol-1-ium-5-sulfonate is a valuable tool for bioconjugation and drug delivery applications, as it can improve the stability, specificity, and pharmacokinetics of drugs, and enable targeted delivery to specific cells or tissues.
