Description

Pentaethylene Glycol Dimethanesulfonate is a high-purity, bifunctional alkylating agent primarily used as a key synthetic intermediate in advanced organic chemistry. Its value lies in its ability to introduce specific spacer units and reactive termini in the controlled synthesis of complex molecules, such as specialized polymers, dendrimers, and pharmaceutical linkers. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise molecular construction for product development.

Application

• Pharmaceutical Intermediate: Critical building block for the synthesis of active pharmaceutical ingredients (APIs), prodrugs, and targeted drug delivery systems.
• Polymer & Dendrimer Synthesis: Used as a cross-linking agent or monomer to create polyethylene glycol (PEG)-based polymers, hydrogels, and precisely branched macromolecular structures.
• Bioconjugation & Linker Chemistry: Facilitates the attachment of drugs, dyes, or other functional groups to proteins, antibodies, or nanoparticles for diagnostic and therapeutic applications.
• Agrochemical Research: Serves as an intermediate in developing novel herbicides, pesticides, and plant growth regulators with tailored properties.
• Material Science: Employed in the creation of specialty surfactants, lubricants, and surface-modifying agents requiring specific chain lengths and terminal functionality.
• Chemical Biology Probes: Useful for synthesizing molecular probes and tools to study biological processes and enzyme mechanisms.

Quality Control

Our Pentaethylene Glycol Dimethanesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high chemical purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
