206265-98-7 Usage
Description
t-boc-N-amido-PEG7-amine is a PEG linker with an amino group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The Boc group can be deprotected under mild acidic conditions to form the free amine.
Uses
O-(2-AMINOETHYL)-O'-(2-(BOC-AMINO)ETHYL) is a polyethyleneglycol (PEG) derivative used as a reagent in the preparation biotinylated spacers present in glucose-transporter probes.
General Description
Our highly purified mono-protected homobifunctional polyethylene glycols display oligomer purities of more than 90%. This extremely narrow distribution of oligomers ensures homogeneous products in many applications such as conjugation reactions or introduction of solubilizing units or spacers.
Check Digit Verification of cas no
The CAS Registry Mumber 206265-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,2,6 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 206265-98:
(8*2)+(7*0)+(6*6)+(5*2)+(4*6)+(3*5)+(2*9)+(1*8)=127
127 % 10 = 7
So 206265-98-7 is a valid CAS Registry Number.
