5-METHYLCHRYSENE Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
Three of the listed PAHs (dibenz[a,h]acridine, dibenz[a,j]acridine, and 7H-dibenzo[c,g]carbazole) contain a nitrogen atom as part of a ring and therefore are classified as heterocyclic PAHs. The PAHs can exist as leaflets, plates, needles, or at room temperature and range in color from colorless to yellow, green or blue. All PAHs are soluble in water and slightly soluble in ethanol, acetone or acid; most are soluble in benzene. Physical and chemical properties of the 15 PAHs are listed in the table below. In addition to the properties listed in the table, benzo[a]pyrene has a specific gravity of 1.351 and a vapor density relative to air of 8.7, and dibenzo[a,h]anthracene has a specific gravity of 1.282 (HSDB 2009).
Verwenden
5-Methylchrysene is one of the methylated chrysenes (MeChry), as an aryl hydrocarbon receptor (AhR) agonist. Methylated chrysenes (MeChry) are important cigarette smoke constituents and 5-MeChry has been listed as possibly carcinogenic to humans. 5-Methylchrysene is a possible carcinogenic agent.
Allgemeine Beschreibung
Purple crystals. Water insoluble.
Air & Water Reaktionen
Dust/air mixture may ignite and explode. Insoluble in water.
Reaktivit?t anzeigen
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 5-METHYLCHRYSENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
Sicherheitsprofil
Confirmed carcinogen
with experimental carcinogenic,
neoplastigenic, and tumorigenic data.
Mutation data reported. When heated to
decomposition it emits acrid smoke and
irritating fumes.
Carcinogenicity
The 15 individual PAHs are reasonably anticipated to be human carcinogens
based on sufficient evidence of carcinogenicity from studies in experimental animals.
