Chemical Structure
Description
The occurrence of N-(Azido-PEG3)-N-bis(PEG3-Boc) 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.
N-(Azido-PEG3)-N-bis(PEG3-Boc) (CAS 2055042-56-1) is a high-purity analytical reference standard with the molecular formula C34H66N4O13 and a molecular weight of 738.91 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, N-(Azido-PEG3)-N-bis(PEG3-Boc) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 738.91 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).
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-Boc) 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.
