Description
1,2,3-PROPANETRIOL GLYCIDYL ETHER, also known as the polyglycidyl ether of substituted glycerine, is a reaction product of epichlorohydrin and glycerin. It is of uniform composition, although the exact molecular arrangement is not known.
Uses
Used in Adhesive Industry:
1,2,3-PROPANETRIOL GLYCIDYL ETHER is used as a component in conjunction with epoxy resins for the manufacture of adhesives. It enhances the adhesive properties and contributes to the overall performance of the final product.
Carcinogenicity
Carcinomas were produced on
the skin of mice painted with the material from once to
thrice weekly over a period of a year. No tumors were
produced on rabbit ears in a similar test. Sarcomas were
produced in rats by subcutaneous injection. When fed to
strain A mice at a concentration of 0.2% in the diet, there was
no increase in the incidence of spontaneous pulmonary
adenomas compared to controls. In a 6 month tumor
promotion study in mice, the material was assessed for both
tumor promotion and tumor initiation compared to positive
controls of dimethylbenzanthracene (DMBA) and tetradecanoyl
phorbol acetate (TPA), respectively. Test materials
were applied in 0.1mL quantities twice weekly for 26 weeks,
with initiation applications beginning on test day 2 and
promotion applications beginning on test day 6. Results
for initiation were inconclusive, since a small number of
skin masses were observed; however, the authors potentially
attributed these to high doses of TPA resulting in repeated
injury and healing cycles. As no lesions were observed with
the material in combination with DMBA, it was judged to
have no potential for tumor promotion.
Check Digit Verification of cas no
The CAS Registry Mumber 25038-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,3 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25038-04:
(7*2)+(6*5)+(5*0)+(4*3)+(3*8)+(2*0)+(1*4)=84
84 % 10 = 4
So 25038-04-4 is a valid CAS Registry Number.
