Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 406.91 g/mol gives Fmoc-NH-PEG2-C2-NH2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Fmoc-NH-PEG2-C2-NH2 (CAS 868599-73-9) is a high-purity analytical reference standard with the molecular formula C21H26N2O4HCl and a molecular weight of 406.91 g/mol.
The molecular framework of Fmoc-NH-PEG2-C2-NH2 (C21H26N2O4HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Fmoc-NH-PEG2-C2-NH2 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.
