Ethanolamine Technical 99.95

Ethanolamine is the second-most-abundant head group for phospholipids, substances found in biological membranes (particularly those of prokaryotes), e.g., phosphatidylethanolamine. I

Ethidium Bromide

Ethidium bromide is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis.Its core heterocyclic moiety is generically known as a phenanthridine, an isomer of which is the fluorescent dye acridine.Ethidium bromide is commonly used to detect nucleic acids in molecular biology laboratories. In the case of DNA this is usually double-stranded DNA from PCRs, restriction digests.Ethidium bromide is not regulated as hazardous waste at low concentrations,but is treated as hazardous waste by many organizations.

Properties Suppliers
Ethyl Acrylate

Ethyl acrylate is an organic compound primarily used in the preparation of various polymers. It is a clear liquid with an acrid penetrating odor.Ethyl acrylate is used in the production of polymers including resins, plastics, rubber, and denture material.

Properties Suppliers
Ethyl Benzoate

Ethyl benzoate is the ester formed by the condensation of benzoic acid and ethanol. As with many volatile esters, ethyl benzoate has a pleasant odor which could be described similar to wintergreen mint. It is a component of some artificial fruit flavors.

Properties Suppliers
Ethyl acetoacetate

Ethyl acetoacetate is a organic compound ethyl acetoacetate is the ethyl ester of acetoacetic acid. It is mainly used as a chemical intermediate in the production of a wide variety of compounds, such as amino acids, analgesics, antibiotics, antimalarial agents, antipyrine and aminopyrine, and vitamin B1; as well as the manufacture of dyes, inks, lacquers, perfumes, plastics, and yellow paint pigments. Alone, it is used as a flavoring for food.

Ethylene Dichloride

Ethylene Dichloride is a chlorinated hydrocarbon, mainly used to produce vinyl chloride monomer, the major precursor for PVC production. It also used generally as an intermediate for other organic chemical compounds and as a solvent. As a good apolar aprotic solvent, 1,2-dichloroethane is used as degreaser and paint remover. In the laboratory it is occasionally used as a source of chlorine, with elimination of ethene and chloride.

Ethylenediaminetetraacetic Acid

Ethylenediaminetetraacetic acid is a polyamino carboxylic acid and a colourless, water-soluble solid. Its conjugate base is named ethylenediaminetetraacetate. It is widely used to dissolve scale. Its usefulness arises because of its role as a hexadentate ligand and chelating agent, i.e. its ability to "sequester" metal ions such as Ca2+ and Fe3+. In the textile industry, it prevents metal ion impurities from modifying colours of dyed products. In the pulp and paper industry, EDTA inhibits the ability of metal ions, especially Mn2+, from catalyzing the disproportionation of hydrogen peroxide, which is used in "chlorine-free bleaching." In similar manner, EDTA is added to some food as a preservative or stabilizer to prevent catalytic oxidative decolouration, which is catalyzed by metal ions. In personal care products, it is added to cosmetics to improve their stability toward air. It is used to bind metal ions in the alternative medical practice of chelation therapy, e.g., for mercury and lead poisoning. It is used in a similar manner to remove excess iron from the body. In the laboratory, EDTA is widely used for scavenging metal ions. In biochemistry and molecular biology, ion depletion is commonly used to deactivate metal-dependent enzymes, either as an assay for their reactivity or to suppress damage to DNA or proteins. In analytical chemistry, EDTA is used in complexometric titrations and analysis of water hardness or as a masking agent to sequester metal ions that would interfere with the analyses.
