Chemical Structure
Description
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.
1,4,8,11-Tetrakis(diethylaminocarbonylmethyl)-1,4,8,11-tetraazacyclotetradecane (CAS 126320-56-7) is a high-purity analytical reference standard with the molecular formula C34H68N8O4 and a molecular weight of 652.95 g/mol.
The molecular framework of 1,4,8,11-Tetrakis(diethylaminocarbonylmethyl)-1,4,8,11-tetraazacyclotetradecane (C34H68N8O4) 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.
