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 N-(m-PEG4)-N'-(PEG4-acid)-Cy5.
N-(m-PEG4)-N'-(PEG4-acid)-Cy5 (CAS 2107273-32-3), molecular formula C45H65N2O10Cl and molecular weight 829.47 g/mol, is a CATO reference standard with documented purity and traceability.
N-(m-PEG4)-N'-(PEG4-acid)-Cy5 (C45H65N2O10Cl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), N-(m-PEG4)-N'-(PEG4-acid)-Cy5 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.
