Chemical Structure
Description
The occurrence of Azido-PEG1-methyl ester is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Azido-PEG1-methyl ester (CAS 1835759-80-2) is a high-purity analytical reference standard with the molecular formula C6H11N3O3 and a molecular weight of 173.17 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Azido-PEG1-methyl ester is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Azido-PEG1-methyl ester 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.
