General description
Redi-Dri™ technology eliminates clumping and the need for complicated procedures to keep your salts free-flowing. Keeping your salts dry helps improve your results by giving accurate measurements and easier-to-handle salts and buffers. Rather than drying your salts in an oven or desiccator or breaking them apart manually, Redi-Dri™ ensures that your salts will remain easy-to-use for months without worrying about anti-caking agents. Even after repeated openings you can be assured that your results are always accurate. Redi-Dri™ saves you time, energy and money by keeping your salts usable for longer!
Application
- Conversion of aromatic primary amines to the corresponding nitro compounds in the presence of tert-butyl hydroperoxide as oxidant.
- Conversion of aryl halide to aryl iodides in the presence of nickel catalysts.
- Preparation of sulfonated oxindoles from activated alkenes and sulfonylhydrazides in water and in the presence of 8-crown-6 and tert-butyl hydroperoxide.
Features and Benefits
- Increased efficiency – Eliminate time and effort of loosening hardened powders
- Safety – Avoid risks of using tools of force to break up clumps
- Economy – Faster preparation and solvation increase productivity and reduce costs
- Assured quality – Excellent, expert-tested quality with no anti-caking agents
- Flexible volumes – Available from research amounts to scale-up quantities
