Package & Storage:

Package: Fluorinated Bottle, 25kg/Drum, 160kg/Drum or according to customer's requirement

Storage Condition: Tightly closed to prevent from leaking and touching water. Stored in cool, vent and dry places, far from fire and heat source. 

Highly Flammable: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.





N,N,N',N'-Tetramethylethylenediamine (TEMED or TMEDA) (CAS: 110-18-9) is used as polymerization accelerator in gel electrophoresis, solvent and oxidizing reagent. TEMED is a tertiary amine base used to catalyze the formation of free radicals from ammonium persulfate or riboflavin. The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix which can be used for sieving macromolecules. For biochemical reagents, water treatment agent, quaternary ammonium salts as intermediate raw material, also used in biochemical research, organic synthesis, cross-linked polymeric catalyst. TEMED is a free radical stabilizer used as a catalyst with APS (Ammonium persulfate, sc-202946) to promote polymerization of Acrylamide/bis-Acrylamide gels. Also employed as a ligand for metal ions as it forms stable complexes with many metal halides, e.g. zinc chloride and copper(I) iodide, giving complexes that are soluble in organic solvents. In such complexes, TEMED serves as a bidentate ligand.  Ready-to-use acrylamide solutions are available for your convenience: Acrylamide Solution, 40% (sc-3721) and N,N′-Methylenebis-Acrylamide, 2% (sc-3719). It is widely employed both as a ligand for metal ions and as a catalyst in organic polymerisation.
