Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, N-(Azido-PEG3)-N-bis(PEG3-acid) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 626.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
N-(Azido-PEG3)-N-bis(PEG3-acid) (CAS 2055042-57-2) is a high-purity analytical reference standard with the molecular formula C26H50N4O13 and a molecular weight of 626.69 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-(Azido-PEG3)-N-bis(PEG3-acid) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
