782475-35-8 Usage
Description
Bromo-PEG3-acid is a PEG linker containing a bromide group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.Uses
This is a crosslinker with a bromo group on one end and a carboxyl group on the other end. The compound contains three PEG units to help improve solubility.Check Digit Verification of cas no
The CAS Registry Mumber 782475-35-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,2,4,7 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.Calculate Digit Verification of CAS Registry Number 782475-35:
(8*7)+(7*8)+(6*2)+(5*4)+(4*7)+(3*5)+(2*3)+(1*5)=198
198 % 10 = 8
So 782475-35-8 is a valid CAS Registry Number.
