For procurement professionals navigating the complex landscape of chemical sourcing, understanding the technical nuances of key intermediates like Diethylene Glycol Ditosylate (CAS 7460-82-4) is crucial. This bifunctional molecule, often utilized as a PEG-based linker, plays a significant role in advanced synthetic chemistry, particularly in the development of PROTACs and other targeted therapeutic agents. Ensuring a reliable supply of high-purity material from reputable sources is a primary concern for R&D departments and manufacturing facilities alike.

Diethylene Glycol Ditosylate is characterized by its chemical formula C18H22O7S2 and a molecular weight of approximately 414.49 g/mol. Its structure, featuring two tosylate ester groups attached to the terminal carbons of a diethylene glycol chain, makes it an excellent bifunctional electrophile. This property allows it to react readily with nucleophiles, facilitating the formation of covalent bonds in multi-step syntheses. The tosylate groups are well-known for being good leaving groups, which simplifies synthetic strategies and often leads to higher yields compared to other activating groups. The diethylene glycol core provides a flexible linker of a specific length, which is often a critical parameter in the design of biologically active molecules.
