Cbz-NH-PEG2-CH2COONHS CAS CATO-C4X-25763 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cbz-NH-PEG2-CH2COONHS.

Cbz-NH-PEG2-CH2COONHS (CAS CATO-C4X-25763) is a high-purity analytical reference standard with the molecular formula C18H22N2O8 and a molecular weight of 394.38 g/mol.

The molecular framework of Cbz-NH-PEG2-CH2COONHS (C18H22N2O8) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. 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).

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), Cbz-NH-PEG2-CH2COONHS 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.
