N-nitrosodibenzylamine C화학적 특성, 용도, 생산
화학적 성질
Yellow Low Melting Solid
용도
N-Nitrosodibenzylamine (NDBzA) is mutagenic to Salmonella typhimurium and induces DNA strand breaks in isolated rat hepatocytes.
생산 방법
Human exposure to NDBzA was not suspected,
but then there were reports of the compound in
hams wrapped in rubber netting. Concentrations
of NDBzA from 10 to 100 ppb were common, and some were
as high as 512 ppb. Like other nitrosamines in rubber,
NDBzA arose by nitrosation of dialkylamino compounds (in
this case dibenzyl-) during manufacture.
Safety Profile
Moderately toxic by ingestion.Mutation data reported. When heated to decomposition itemits toxic vapors of NOx
Carcinogenicity
There is a single report of a test of nitrosodibenzylamine for
carcinogenicity in rats using high doses and that is
completely negative; in contrast, nitrosobenzylphenylamine
is a weak, but definite, esophageal carcinogen in
rats. NDBzA is not mutagenic to bacteria in the
presence or absence of rat liver microsomes.
Although there is no information about metabolism and
activation of NDBzA, the alpha-acetoxy derivative (which
presumably is the ester of the alpha-hydroxy derivative that
would be formed in vivo) is both carcinogenic to rats and
mutagenic to bacteria.
