139115-91-6 Usage
Description
N-Boc-PEG2-alcohol is a PEG linker containing a hydroxyl group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The Boc group can be deprotected under mild acidic conditions to form the free amine.
Uses
2-[2-(Boc-amino)ethoxy]ethanol is N-terminal protected 2-(2-aminoethoxy)ethanol. It is generally used as a molecular spacer/linker. Some of such applications are:Synthesis of biotinylated HaloLigands to prepare quantum dot adducts for HaloTag protein-mediated specific labeling of live cells.It is one of the key precursors for the total synthesis of tyroscherin and photo-activatable tyroscherin-based affinity reagent used for identification of tyroscherin binding proteins.It can be used to link HaloTag enzyme with fluorescent zinc indicator, ZIMIR to monitor the dynamics of regulated secretion of zinc in real time.It can also be used to synthesize amphiphiles for DNA and siRNA delivery.
Check Digit Verification of cas no
The CAS Registry Mumber 139115-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,1 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139115-91:
(8*1)+(7*3)+(6*9)+(5*1)+(4*1)+(3*5)+(2*9)+(1*1)=126
126 % 10 = 6
So 139115-91-6 is a valid CAS Registry Number.
