Description

Polyethylene Glycol(200)Di(β-(4(Pacetyl Phenyl) Piperazine))Propionate is a specialized bifunctional PEG derivative designed for advanced conjugation and linker applications. This compound matters for its ability to introduce both solubility and a reactive piperazine-acetylphenyl moiety, enabling precise chemical modifications and controlled release strategies. It is primarily needed by pharmaceutical R&D teams and fine chemical manufacturers developing targeted drug delivery systems, prodrugs, and sophisticated polymer conjugates.

Application

• As a functionalized linker in the synthesis of antibody-drug conjugates (ADCs) and other bioconjugates.
• As a solubilizing and spacer component in prodrug design to enhance bioavailability and control release kinetics.
• In the development of polymer-drug conjugates for targeted cancer therapies and other controlled-release formulations.
• For the surface modification of nanoparticles and biomaterials to impart stealth properties and introduce specific chemical handles.
• As a key intermediate in advanced organic synthesis for creating complex molecules with tailored PEGylation.
• In research-grade chemical tools for studying receptor-ligand interactions and signal transduction pathways.

Quality Control

Our Polyethylene Glycol(200)Di(β-(4(Pacetyl Phenyl) Piperazine))Propionate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting research and pharmaceutical-grade standards. Comprehensive Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
