VUN 44557, also known as Azido-PEG4-Amido-Tris, also known as Azido-PEG4-Amido-tri-(carboxyethoxymethyl)-methane, is a multi-arm PEG containing an azide group and three hydroxyl groups. The azide group enables Click Chemistry. The indicated molecular weight of the multi-arm PEG is the sum of the molecular weights of all the arms. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. This product has no formal name. For the convenience of scientific communication, we named it by combining its InChi Key (3 letters from the first letter of each section) with the last 5 digits of its CAS#, according to MedKoo Chemical Nomenclature (https://www.medkoo.com/page/naming).
