Chemical Structure

N-Methyl-N'-methyl-O-(m-PEG4)-O'-(azide-PEG4)-Cy3 CAS 2107273-64-1 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-Methyl-N'-methyl-O-(m-PEG4)-O'-(azide-PEG4)-Cy3.

CATO supplies N-Methyl-N'-methyl-O-(m-PEG4)-O'-(azide-PEG4)-Cy3 (CAS 2107273-64-1), a certified reference material (molecular formula C44H66N5O10Cl, MW 860.49 g/mol) for analytical method development and quality control.

Structurally, N-Methyl-N'-methyl-O-(m-PEG4)-O'-(azide-PEG4)-Cy3 (C44H66N5O10Cl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 860.49 g/mol, it falls into the high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
