The pursuit of novel therapeutic modalities has led to the rise of targeted protein degradation (TPD), a powerful approach that seeks to eliminate disease-causing proteins rather than merely inhibiting their activity. Central to TPD strategies, such as Proteolysis-Targeting Chimeras (PROTACs), are linker molecules that bridge target protein binders with E3 ligase recruiters. NINGBO INNO PHARMCHEM CO.,LTD. supplies tert-Butyl N-[2-[2-(2-bromoethoxy)ethoxy]ethyl]carbamate, identified by CAS number 165963-71-3, a critical chemical intermediate that significantly aids in the synthesis of these advanced therapeutics.

The molecule's structure, characterized by a polyethylene glycol (PEG) spacer flanked by a Boc-protected amine and a bromoethyl group, makes it exceptionally well-suited for constructing PROTACs and other TPD agents. The PEG linker provides optimal spacing and flexibility, which are crucial for the efficient formation of the ternary complex required for ubiquitination and subsequent protein degradation. The Boc-protected amine offers a handle for conjugation to one part of the PROTAC, typically the E3 ligase-binding ligand, and can be readily deprotected under mild acidic conditions. The bromide terminus, on the other hand, serves as a reactive site for attaching the target protein-binding ligand, often via nucleophilic substitution with a thiol or amine group present on the ligand. This modular approach allows researchers to easily swap and optimize different components of the TPD molecule.

The synthesis of PROTACs demands high-purity reagents to ensure the integrity and efficacy of the final product. NINGBO INNO PHARMCHEM CO.,LTD. is a reputable supplier committed to delivering intermediates like CAS 165963-71-3 with exceptional purity, typically exceeding 97%. This high purity is essential because even trace impurities can interfere with the complex assembly of PROTACs or lead to off-target effects when the synthesized molecules are used in biological assays or therapeutic applications. The availability of such reliable building blocks empowers researchers to buy with confidence, knowing they are using materials of consistent quality for their critical work in protein degradation research.

The economic viability and scalability of synthesizing TPD agents are also greatly influenced by the availability of efficient linker molecules. By providing a pre-functionalized, high-quality intermediate like tert-Butyl N-[2-[2-(2-bromoethoxy)ethoxy]ethyl]carbamate, NINGBO INNO PHARMCHEM CO.,LTD. helps to streamline the synthetic process, reduce the number of steps, and potentially lower the overall cost of producing these innovative therapeutics. This makes it more accessible for research institutions and pharmaceutical companies to explore the vast therapeutic potential of targeted protein degradation.

In conclusion, CAS 165963-71-3 is more than just a chemical compound; it is an enabler of groundbreaking therapeutic strategies. Its unique design and the reliable supply from manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. are crucial for the advancement of targeted protein degradation, offering hope for more effective treatments for a range of diseases.
