DBCO-dPEG <SUP>®</SUP><SUB>4</SUB>-TFP ester CAS 2247993-79-7

Description

The occurrence of DBCO-dPEG <SUP>®</SUP><SUB>4</SUB>-TFP ester is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies DBCO-dPEG <SUP>®</SUP><SUB>4</SUB>-TFP ester (CAS 2247993-79-7), a certified reference material (molecular formula C37H38F4N2O8, MW 714.70 g/mol) for analytical method development and quality control.

The molecular framework of DBCO-dPEG <SUP>®</SUP><SUB>4</SUB>-TFP ester (C37H38F4N2O8) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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.

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.
