一、基本信息

【性质简介】：(4E) - TCO-NHS ester is a compound with unique properties, which can exist in solid or viscous liquid forms, mainly depending on the molecular weight of the PEG (polyethylene glycol) it binds to. In most cases, it presents a pure white solid form, giving people a fresh ａnd delicate feeling. In the field of chemistry, the TCO component of (4E) - TCO-NHS ester exhibits impressive site-specific binding ability, which is achieved through click chemistry. This click chemistry method enables precise binding of (4E) - TCO-NHS ester with biomolecules such as antibodies, proteins, or probes, providing great convenience for biomedical research.

It is worth mentioning that the TCO part of the (4E) - TCO-NHS ester can react with tetrazine through a mechanism called anti electron demand Diels Alder cycloaddition reaction. This reaction process is not only efficient, but also capable of forming stable dihydropyridazine bonds, ensuring a stable connection between the (4E) - TCO-NHS ester ａnd the target molecule. The formation of this stable dihydropyridazine bond provides a powerful tool for labeling, tracing, ａnd detection in biomedical research. Whether in drug development, biological imaging, or protein interaction research, (4E) - TCO-NHS ester has demonstrated its unique value ａnd broad application prospects.
