COA OF 4-Ethylphenol


CAS NO:123-07-9

In wine and beer, 4-EP is produced by the spoilage yeast Brettanomyces. When it reaches concentrations greater than the sensory threshold (140 µg/L) it can give the wine aromas described as barnyard, medicinal, band-aids, and mousy. In certain Belgian beer styles, a high 4-EP level may be desirable; however, very high levels of the compound in wine can render it undrinkable. The level of 4-EP is roughly proportional to Brettanomyces concentration and activity, and can therefore be used as an indicator of the yeast's presence. There are significant differences between strains of Brettanomyces in their ability to produce 4-EP.

4-EP is also a component of castoreum, the exudate from the castor sacs of the mature North American beaver (Castor canadensis) and the Eurasian beaver (Castor fiber), used in perfumery.

COA OF 4-Nitroanisole 97%


CAS NO:100-17-4

-Nitroanisole was used as probe to determine Π^* of Kamlet-Taft solvent parameters and high pressure and supercritical water in the temperature range of 16-420 °C^[1]. 4-Nitroanisole was used as carbon and energy supplement for the isolation of Rhodococcus strains.

INFORMATION OF Neodymium oxide: Neodymium(III) oxide or neodymium sesquioxide is the chemical compound composed of neodymium and oxygen with the formula Nd₂O₃. It forms very light grayish-blue hexagonal crystals.^[1] The rare earth mixture didymium, previously believed to be an element, partially consists of neodymium(III) oxide
Neodymium(III) oxide is used to dop glass, including sunglasses, to make solid-state lasers, and to color glasses and enamels.^[3]Neodymium-doped glass turns purple due to the absorbance of yellow and green light and is used in welding goggles.^[4] Some neodymium-doped glass is dichroic; that is, it changes color depending on the lighting. One kind of glass named for the mineral alexandrite appears blue in sunlight and red in artificial light.^[5] About 7000 tonnes of neodymium(III) oxide are produced worldwide each year. Neodymium(III) oxide is also used as a polymerization catalyst.
Neodymium(III) oxide is formed when neodymium(III) nitride or neodymium(III) hydroxide is burned in air
