The PEG spacer can provide stealth properties to nanoparticles, reducing their clearance and enhancing their circulation time in the body.
Used in Surface Modification:
HS-PEG4-CH2CH2COOH is used as a surface modification agent in various industries, including electronics and materials science. The thiol group can bind to gold or silver surfaces, allowing for the attachment of functional groups or the formation of self-assembled monolayers for sensor development, molecular electronics, or other applications.
Used in Cosmetics and Personal Care:
In the cosmetics and personal care industry, HS-PEG4-CH2CH2COOH is used as a stabilizing and conditioning agent. The hydrophilic PEG spacer can improve the solubility and compatibility of various ingredients, while the reactive groups can be used to attach active components or improve the texture and performance of formulations.
Check Digit Verification of cas no
The CAS Registry Mumber 749247-06-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,2,4 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 749247-06:
(8*7)+(7*4)+(6*9)+(5*2)+(4*4)+(3*7)+(2*0)+(1*6)=191
191 % 10 = 1
So 749247-06-1 is a valid CAS Registry Number.
