Chemical Structure

Boc-NH-PEG4-NHS ester CAS 859230-20-9 chemical structure

Description

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.

Boc-NH-PEG4-NHS ester (CAS 859230-20-9) is a high-purity analytical reference standard with the molecular formula C20H34N2O10 and a molecular weight of 462.49 g/mol.

Based on its molecular formula C20H34N2O10, Boc-NH-PEG4-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 462.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), Boc-NH-PEG4-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.
