68130-97-2 Usage
Uses
Used in Industrial and Commercial Applications:PEI is used as a dispersing agent, binder in paper production, and flocculant in wastewater treatment processes due to its adhesive, flocculating, and film-forming properties.
Used in Adhesives, Coatings, and Textiles Production:
PEI is used as a key component in the production of adhesives, coatings, and textiles, contributing to their adhesive, binding, and film-forming characteristics.
Used in Personal Care Products and Pharmaceuticals:
PEI is used in the formulation of personal care products and pharmaceuticals, taking advantage of its cationic polyelectrolyte nature and ability to interact with various substances.
Used in Biomedical Engineering:
PEI is used in gene and drug delivery systems, tissue engineering, and medical diagnostic applications, leveraging its properties to facilitate the delivery and interaction of biological molecules.
Note: When handling PEI, proper safety precautions should be taken due to its potential to cause irritation to the skin, eyes, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 68130-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,3 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.Calculate Digit Verification of CAS Registry Number 68130-97:
(7*6)+(6*8)+(5*1)+(4*3)+(3*0)+(2*9)+(1*7)=132
132 % 10 = 2
So 68130-97-2 is a valid CAS Registry Number.
