Description
Tetrazine-PEG5-NHS Ester is a PEG linker containing a tetrazine group and an NHS ester which is very reactive with amine(NH2)-containing molecule. Methyltetrazine enable fast click reaction with TCO (trans-cycloctene).
Uses
Tetrazine-PEG5-NHS ester (Tz-PEG5-NHS) can be used in click chemistry applications such as the preparation of chitosan-polyacrylamide microspheres utilizing selective tetrazine-trans-cyclooctene (Tz-TCO) ligation and the construction of copper-64 radiolabeled antibody by the click reaction.
General Description
Tetrazine-PEG5-NHS ester has an N-hydroxysuccinimide (NHS) ester that can be reacted with primary amines and tetrazine, which is reactive to trans-cyclooctenes. Hydrogen substituted tetrazines demonstrate exceptionally fast kinetics, generally at least 10-fold faster compared to methyl substituted tetrazines. The aqueous solubility of this reagent is substantially enhanced by a hydrophilic polyethylene glycol (PEG) spacer arm.
Check Digit Verification of cas no
The CAS Registry Mumber 1682653-80-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,8,2,6,5 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1682653-80:
(9*1)+(8*6)+(7*8)+(6*2)+(5*6)+(4*5)+(3*3)+(2*8)+(1*0)=200
200 % 10 = 0
So 1682653-80-0 is a valid CAS Registry Number.
