Description
Diisononyl phthalate (DINP) is a colorless to light yellow liquid with the empirical formula C26H42O4. It is insoluble in water but soluble in organic solvents. The structural formula of DINP varies due to the presence of several isomers in the iso-alcohols used in its manufacture.

Production Methods
DINP is manufactured by the reaction of phthalic anhydride
with isononanol in the presence of an acid catalyst.
Flammability and Explosibility
Nonflammable
Carcinogenicity
As stated, there have been two
carcinogenesis studies in F344 rats and one in
B6C3F1 mice. An increased incidence of hepatocellular
neoplasms (i.e., adenomas and carcinomas) is observed in
both rats and mice. An increased incidence of renal cell
carcinomas and mononuclear cell leukemia has also been
described. These studies establish that at dose levels of
approximately 600 mg/kg/day, DINP can induce hepatocellular
carcinoma in rats and mice. As there was evidence of
peroxisomal proliferation at the carcinogenic doses in both
species, it seems most likely that this was the mechanism for
hepatocellular carcinoma induction. The renal cell
carcinomas observed in the male rats were associated with
the induction of α 2u-globulin, indicating that it was a
sex- and species-specific effect. Kidney tumors that are the
consequence of α 2u-globulin induction are not considered to
be clinically relevant to humans.MNCL is a tumor type
that occurs spontaneously at a high and variable frequency in
F344 rats. Because there is no human equivalent, MNCL is
not considered to be relevant to humans.
Check Digit Verification of cas no
The CAS Registry Mumber 68515-48-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,1 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68515-48:
(7*6)+(6*8)+(5*5)+(4*1)+(3*5)+(2*4)+(1*8)=150
150 % 10 = 0
So 68515-48-0 is a valid CAS Registry Number.
