BETA-PINENE (127-91-3, 25719-60-2, 127-91-3, 18172-67-3)
terebenthene · terbenthene
beta-Pinene (β-pinene) is a monoterpene, an organic compound found in plants. It is one of the two isomers of pinene, the other being α-pinene. It is colorless liquid soluble in alcohol, but not water.
CHRYSENE (65996-93-2, 50-32-8, 218-01-9)
Chrysene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C 18H 12 that consists of four fused benzene rings. It is a natural constituent of coal tar, from which it was first isolated and characterized. It is also found in creosote at levels of 0.5-6 mg/kg.
Tasosartan is an angiotensin II receptor antagonist. It was withdrawn from FDA review by the manufacturer after phase III clinical trials showed elevated transaminases (a sign of possible liver toxicity) in a significant number of participants given the drug.
naphthalene (91-20-3, 68412-25-9)
Naphthalene is an organic compound with formula C 10H 8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings.
2-CHLORONAPHTHALENE (1321-65-9, 1335-88-2, 91-58-7)
2-Chloronaphthalene is an organochlorine chemical compound, a chlorinated derivative of naphthalene. Its chemical formula is C 10H 7Cl. The compound is an isomer for 1-chloronaphthalene.
1,1,1,2-TETRACHLOROETHANE (23425-39-0, 630-20-6)
1,1,1,2-Tetrachloroethane is a chlorinated hydrocarbon. It is a colorless liquid with a sweet chloroform-like odor. It is used as a solvent and in the production of wood stains and varnishes.
Anisole, p-propenyl- (104-46-1, 50770-19-9)
Anethole (anise camphor) is an organic compound that is widely used as a flavoring substance. It is a derivative of phenylpropene, a type of aromatic compound that occurs widely in nature, in essential oils. It contributes a large component of the odor and flavor of anise and fennel (both in the botanical family Apiaceae), anise myrtle (Myrtaceae), liquorice (Fabaceae), camphor, magnolia blossoms, and star anise (Illiciaceae).
2,4-dimethylphenol titanium (+4) · 2,4-dimethylphenol potassium · 2,4-DMP
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.
Pentachloroethane is a non-flammable but toxic chemical compound of chlorine, hydrogen, and carbon. It is used as a solvent for oil and grease, in metal cleaning, and in the separation of coal from impurities.
benzanthracene · benzo(b)phenanthrene · 1,2-benzanthracene
Benz[a]anthracene or benzo[a]anthracene is a polycyclic aromatic hydrocarbon with the chemical formula C18H12. In February 2014, NASA announced a greatly upgraded database for tracking polycyclic aromatic hydrocarbons (PAHs), including benz[a]anthracene, in the universe. According to scientists, more than 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.
FLUORANTHENE (206-44-0, 76774-50-0)
Fluoranthene is a polycyclic aromatic hydrocarbon (PAH). The molecule can be viewed as the fusion of naphthalene and benzene unit connected by a five-membered ring. Although samples are often pale yellow, the compound is colorless.
P-XYLENE (68650-36-2, 68411-39-2, 106-42-3)
paraxylene · 4-xylene · para-xylene
p-Xylene (para-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The p- stands for para-, indicating that the two methyl groups in p-xylene occupy the diametrically opposite substituent positions 1 and 4.
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.
BUTANE (68514-31-8, 106-97-8, 68476-42-6)
Butane () is an organic compound with the formula C4H10 that is an alkane with four carbon atoms. Butane is a gas at room temperature and atmospheric pressure. The term may refer to either of two structural isomers, n-butane or isobutane (also called "methylpropane"), or to a mixture of these isomers.
