Vat yellow 4 (128-66-5)
7,14-Dibenzpyrenequinone is a yellow synthetic anthraquinone vat dye, known as Vat Yellow 4. It is a bright yellow solid. This dye is used mostly as a dye for textiles and paper.
2-BROMOPHENOL (32762-51-9, 95-56-7)
o-bromophenol · ortho-bromophenol
4-nonylphenol (104-40-5, 68081-86-7, 25154-52-3)
4-tert-nonylphenol · para-nonylphenol
Nonylphenols are a family of closely related organic compounds called alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics.
ANTHRACENE (120-12-7, 54261-80-2, 90640-80-5)
anthracene, sodium salt, ion (1-)
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C14H10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes.
Triphenylmethane, or triphenyl methane, is the hydrocarbon with the formula (C6H5)3CH. This colorless solid is soluble in nonpolar organic solvents and not in water. Triphenylmethane is the basic skeleton of many synthetic dyes called triarylmethane dyes, many of them are pH indicators, and some display fluorescence.
para-bromophenol · p-bromophenol
FLUORENE (2299-68-5, 86-73-7)
Fluorene , or 9H-fluorene, is a polycyclic aromatic hydrocarbon. It forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. It is combustible.
