Vat yellow 4 (128-66-5)  
dibenzo(b,def)chrysene-7,14-dione
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.

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.
FLUORENE (2299-68-5, 86-73-7)  
9H-fluorene
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.
CADALENE (483-78-3)  
Cadalene or cadalin (4-isopropyl-1,6-dimethylnaphthalene) is a polycyclic aromatic hydrocarbon with a chemical formula C15H18 and a cadinane skeleton. It is derived from generic sesquiterpenes, and ubiquitous in essential oils of many higher plants. Cadalene, together with retene, simonellite and ip-iHMN, is a biomarker of higher plants, which makes it useful for paleobotanic analysis of rock sediments.
2-METHYLNAPHTHALENE (7419-61-6, 91-57-6)  
2-methylnaphthalene, methyl-13C-labeled  ·  2-methylnaphthalene, lithium salt, ion(1-)  ·  2-methylnaphthalene, naphthalene-1-(13)C-labeled
2-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH). On February 22, 2014, NASA announced a greatly upgraded database for detecting and monitoring PAHs, including 2-methylnaphthalene, in the universe. According to NASA scientists, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.
1-METHYLNAPHTHALENE (90-12-0, 1321-94-4)  
1-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH). It has a cetane number of zero, and was previously used as the lower reference for cetane number. However, due to the expense and handling difficulty of 1-methylnaphthalene, it was replaced in this capacity by isocetane, with a CN of 15.
