Lub teeb daj hmoov Benzo[a]pyrene CAS 50-32-8

Khoom Description

Lub teeb daj hmoov Benzo[a]pyrene CAS 50-32-8 yog dab tsi?

Cov tshuaj sib xyaw ua ke rau CAS 50-32-8 yog Benzo [a]pyrene, nrog cov qauv molecular ntawm C₂₀H₁₂ thiab molecular hnyav ntawm 252.31 g / mol. Nws yog polycyclic aromatic hydrocarbon tsim los ntawm tsib angularly fused benzene rings, thiab nws cov qauv molecular tshwj xeeb ua rau nws tus neeg sawv cev polycyclic aromatic hydrocarbon (PAHs) compound.

Benzo [a] pyrene tshwm raws li lub teeb daj crystalline hmoov nyob rau hauv chav tsev kub, nthuav tawm lub melting point ntawm 177-180 degree, boiling point ntawm 495 degree, thiab ceev ntawm 1.35 g / cm³. Nws yooj yim soluble hauv cov kuab tshuaj organic xws li benzene, toluene, thiab chloroform, nrog me ntsis solubility hauv ethanol.

Siv

Hauv kev tshawb fawb txog carcinogenic mechanism, Benzo [a] pyrene yog siv rau hauv kev sim tsiaj (piv txwv li, daim tawv nqaij daim ntawv thov lossis kev tswj hwm qhov ncauj hauv nas) los kawm txog kev cuam tshuam ntawm nws cov metabolites (piv txwv li, BPDE) thiab DNA, nthuav tawm txoj hauv kev molecular ntawm kev hloov noob caj noob ces thiab qog nqaij hlav. Raws li tus qauv tsim tshuaj, nws tshuaj ntsuam cov tshuaj tiv thaiv nrog rau kev tiv thaiv - mutagenic lossis tiv thaiv - mob qog noj ntshav, xws li tshuaj xyuas cov nyhuv inhibitory ntawm cov khoom ntuj (xws li tshuaj yej polyphenols) ntawm lawv cov carcinogenicity. Rau cov qauv tshuaj toxicology, nws ua haujlwm zoo hauv kev kuaj tshuaj toxicity los ntsuas qhov muaj peev xwm carcinogenic txaus ntshai ntawm cov tshuaj tshiab.
