Chemical Structure
Description
The occurrence of N-methyl-N'-methyl-O-(m-PEG4)-O'-(propargyl-PEG4)-Cy3 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-methyl-N'-methyl-O-(m-PEG4)-O'-(propargyl-PEG4)-Cy3 (CAS 2107273-62-9), molecular formula C45H65N2O10Cl and molecular weight 829.47 g/mol, is a CATO reference standard with documented purity and traceability.
N-methyl-N'-methyl-O-(m-PEG4)-O'-(propargyl-PEG4)-Cy3 (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. 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), N-methyl-N'-methyl-O-(m-PEG4)-O'-(propargyl-PEG4)-Cy3 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.
