Naphthol
Naphthol – Definition: Alpha naphthol is a white solid with a characteristic odor. It is soluble in water, alcohol, ether, and chloroform. It is used in the manufacture of dyes, plastics, and also pharmaceuticals.
Amino Naphthol
Amino Naphthol is a synthetic organic compound that is used as a dye intermediate. It is a white solid that is soluble in water. It is used to produce a variety of different dyes, including azo dyes.
Structure of a typical prokaryotic cell
A prokaryotic cell is typically about 1-10 micrometers long and 0.5-1.5 micrometers wide. It has a simple, cylindrical shape with a single plasma membrane and no nucleus or organelles. Therefore the prokaryotic cell’s genetic material is located in the cytoplasm in the form of a single chromosome. Prokaryotic cells surrounded by a cell wall made of peptidoglycan, a type of glycoprotein.
Polarity
Polarity is the orientation of a molecule’s electron orbitals relative to one another. In molecules with a net positive charge, the orbitals point away from the center of the molecule. In molecules with a net negative charge, the orbitals point toward the center of the molecule.
Solubility
Methanol is miscible with water and also most organic solvents.
Alcoholic Alpha Naphthol
An alcoholic naphthol, also known as an aryl naphthol, is a type of organic compound that consists of a benzene ring fused to a naphthol. These compounds are often colorless or pale yellow, and are soluble in organic solvents.
Pyridylazo Naphthol
- A red dye with a structure similar to that of naphthol. It used as a dye for textiles and paper.
- Pyridylazo naphthol is an azo dye with the chemical formula C16H10N4O2. Red dye that used in the textile and paper industries. Therefore the dye has a structure similar to that of naphthol.
- Pyridylazo naphthol used as a dye for textiles and paper. It is a red dye that can used to color a variety of materials.
- The dye has a structure similar to that of naphthol, so it is able to bind to fibers and produce a strong color. Pyridylazo naphthol also resistant to washing, so it can last for a long time.
Furfural and 1 Naphthol
It is a colorless, oily liquid that has a sweet, almond-like odor. 1-naphthol is a white, crystalline solid that has a bitter, phenolic odor. When furfural and 1-naphthol mixed together, they form an orange-colored solution.
