Polystyrene Sulfonyl Chloride
This polymer-bound alkylsulfonyl chloride resin is an equivalent to alkyl sulfonic chloride and can be used in numerous applications. When this resin is treated with nucleophiles, a variety of polymer-bound sulfonates can be created ( e.g. sulfonyl azides, sulfonyl hydrazine) and subsequently used as polymeric supports, polymer-bound reagents or in catalytic organic synthesis. Uses: Application in the "catch and release" strategy, where the resin catches a compound to form a polymer-bound tosylate. purifying the polymer-bound tosylate by washing and subsequent treatment by a nucleophile releases the target product from the resin. a typical application is to form polymer-bound tosylates by loading alcohols to the resin. treatment with nucleophiles like amines, imidazoles or thiols generates the corresponding sec. or tert. amines, alkylimidazoles or thioethers. this resin can also be used as a scavenger for amines, hydrazines and other nucleophiles. Group: Polymer bound sulfonyl chloride. Pack Sizes: 5g, 25g, 100g.

PTFE is generally referred to as "non-stick coating"/"easy-cleaning material"; it is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. Uses: Ptfe is widely used in various occasions where resistance to acid, alkali and organic solvents is required, and is used to make non-stick pans and dry-type transformers. teflon has a soft texture, so it is often used for coatings. when it was first developed, its main application area was the inner wall coating of high-temperature launch rockets. ptfe is also the main component of the green tape.
