1807537-38-7 Usage
Description
Aminooxy-PEG4-acid is a PEG linker containing an aminooxy group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The aminooxy group can be used in bioconjugation. It reacts with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. 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. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended. Aminooxy-PEG4-acid is not stable as a neat compound; it is sold as 1.0M aqueous solution.Check Digit Verification of cas no
The CAS Registry Mumber 1807537-38-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,0,7,5,3 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.Calculate Digit Verification of CAS Registry Number 1807537-38:
(9*1)+(8*8)+(7*0)+(6*7)+(5*5)+(4*3)+(3*7)+(2*3)+(1*8)=187
187 % 10 = 7
So 1807537-38-7 is a valid CAS Registry Number.
