613 Results for: "Gas Chromatography"

Supplier: Honeywell Research Chemicals

Ethyl Acetate is an organic solvent with the structure CH₃-COO-CH₂-CH₃ (C₄H₈O₂). This colorless liquid has a characteristic sweet odor. In the laboratory, mixtures containing ethyl acetate are used in column chromatography and extractions. Ethyl acetate does not work well as a reaction solvent because it is prone to hydrolysis and transesterification. Ethyl acetate is volatile at room temperature and has a boiling point of 77 °C. Suitable for GC and Pesticide Residue Analysis.

Sodium azide used as a preservative for laboratory reagents; a bacteriostatic agent in storage solutions. Inhibits gram negative flora so is therefore included in culture media for the selective isolation of Streptococci and Staphylococci. It has been used to avoid bacterial contamination during RPC-5 column chromatography of DNA fragments.
Catalyst for:
• Oxidative decarboxylation
• Michael addition reactions
Reagent for synthesis of
• Blue fluorescent copolymers
• Metal phosphonates
• Arenes via aminations
Involved in regioselective synthesis of prianosin B
It is also a useful probe reagent, mutagen, and preservative. In hospitals and laboratories, it is a biocide (A biocide is a chemical substance or microorganism which can deter, render harmless, or exert a controlling effect on any harmful organism by chemical or biological means.)
Sodium Azide is an inhibitor of peroxidase, myeloperoxidase, superoxide dismutase, galactose oxidase, catalase, haemoprotein enzymes and O2 evolution in photosynthesis. The mechanism of its inhibition and toxicity may be due to metal ion complexation and displacement from enzyme.
