Description
As a certified reference material (CRM), N-Mal-N-bis(PEG2-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.
N-Mal-N-bis(PEG2-NHS ester) (CAS 2182601-73-4) is a high-purity analytical reference standard with the molecular formula C29H38N4O15 and a molecular weight of 682.63 g/mol.
The molecular framework of N-Mal-N-bis(PEG2-NHS ester) (C29H38N4O15) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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.
