Hazard
Toxic, carcinogen.
Health Hazard
Chlorodiphenyl, 54% chlorine
(Arochlor 1254) , a polychlorinated biphenyl or
PCB, is an irritant of the eyes and mucous membranes. It is toxic to the liver of animals,
and severe exposure may produce a similar
effect in humans. It also causes an acneform
dermatitis (chloracne). It is a liver carcinogen
in animals.
Safety Profile
Confirmed carcinogen
with experimental carcinogenic and
neoplastigenic data. Poison by intravenous
route. Moderately toxic by ingestion and
intraperitoneal routes. Experimental
teratogenic and reproductive effects.
Mutation data reported. When heated to
decomposition it emits toxic fumes of Cl-. Used in heat transfer, hydraulic fluids,
lubricants, and insecticides. See also

Environmental fate
Biological. A strain of Alcaligenes eutrophus degraded 35% of the congeners by dechlorination
under anaerobic conditions (Bedard et al., 1987). Indigenous microbes in the Center Hill
Reservoir, TN oxidized 2-chlorobiphenyl (a congener present in trace quantities) into
chlorobenzoic acid and chlorobenzoylformic acid. Biooxidation of the PCB mixture containing 54
wt % chlorine was not observed (Shiaris and Sayler, 1982).
Soil. In two California soils (foc = 0.3 and 11.3%), 95% of the applied amount was recovered
after 1 yr with no change in the congener composition. In the four remaining soils containing less
organic carbon (0.06 to 1.9%), degradation resulted in preferential loss of congeners with the
lowest molecular weight (Iwata et al., 1973).
Photolytic. PCB-1254 in a 90% acetonitrile/water solution containing 0.2–0.3 M sodium borohydride
and irradiated with UV light (λ = 254 nm) reacted to yield dechlorinated biphenyls. After
16 h, no chlorinated biphenyls were detected. Without sodium borohydride, only 25% of
PCB-1254 were destroyed after 16 h (Epling et al., 1988). In a similar experiment, PCB-1254
(1,000 mg/L) in an alkaline 2-propanol solution was exposed to UV light (λ = 254 nm). After 30
min, all of the PCB-1254 isomers were converted to biphenyl. When the radiation source was
sunlight, only 25% was degraded after a 20-h exposure. But when the sensitizer phenothiazine (5
mM) was added to the solution, photodechlorination of PCB-1254 was complete after 1 h at 350
nm. In addition, when PCB-1254 contaminated soil was heated at about 80 °C in the presence of
di-tert-butyl peroxide, complete dechlorination to biphenyl was observed (Hawari et al., 1992).
Chemical/Physical. When PCB-1254-contaminated sand was treated with a poly(ethylene
glycol)/potassium hydroxide mixture at room temperature, 81% reacted after 6 d forming aryl
poly(ethylene glycols) (Brunelle and Singleton, 1985).
Solubility in water
(wt %): Pyridine (114 at 31 °C), diglycol monoethyl ether (173 at 26 °C), methanol (15 at 26 °C), ethanol
(10 at 27 °C) (Monsanto, 1960)
Check Digit Verification of cas no
The CAS Registry Mumber 11097-69-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,0,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 11097-69:
(7*1)+(6*1)+(5*0)+(4*9)+(3*7)+(2*6)+(1*9)=91
91 % 10 = 1
So 11097-69-1 is a valid CAS Registry Number.
