Chemical Structure
Description
The occurrence of Azido-PEG12-NHS Ester is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Azido-PEG12-NHS Ester (CAS 1108750-59-9) is a high-purity analytical reference standard with the molecular formula C31H57N4O16 and a molecular weight of 741.80 g/mol.
Azido-PEG12-NHS Ester (C31H57N4O16) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
