What is DIBENZO[B,DEF]CHRYSENE?
The Uses of DIBENZO[B,DEF]CHRYSENE
Dibenzo[a,h]pyrene may be used as an analytical reference standard for the quantification of the analyte in the following:
- In environmental samples using liquid chromatography–atmospheric pressure laser ionization–mass spectrometry (LC-APLI-MS).
- In spiked smoke flavorings and baby food products using gas chromatography coupled to mass spectrometry (GC-MS) technique.
Definition
ChEBI: Dibenzo[a,h]pyrene is an ortho- and peri-fused polycyclic arene.
General Description
Yellow odorless crystals or flakes. Water insoluble.
Air & Water Reactions
Dust/air mixtures may ignite and explode. Insoluble in water.
Reactivity Profile
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DIBENZO[B,DEF]CHRYSENE, 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.
Safety Profile
Confirmed carcinogen with experimental carcinogenic and tumorigenic data. When heated to decomposition it emits acrid smoke and irritating fumes. Mutation data reported.
