Boc-NH-PEG3-NHS ester CAS 2250216-93-2

Description

The occurrence of Boc-NH-PEG3-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.

Boc-NH-PEG3-NHS ester (CAS 2250216-93-2), molecular formula C18H30N2O9 and molecular weight 418.44 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H30N2O9, Boc-NH-PEG3-NHS ester contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 418.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Boc-NH-PEG3-NHS 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.
