Chemical Structure
Description
The occurrence of 2,2'-((2-((2-Aminoethyl)amino)ethyl)azanediyl)diethanol is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,2'-((2-((2-Aminoethyl)amino)ethyl)azanediyl)diethanol (CAS 10138-71-3), molecular formula C8H21N3O2 and molecular weight 191.27 g/mol, is a CATO reference standard with documented purity and traceability.
2,2'-((2-((2-Aminoethyl)amino)ethyl)azanediyl)diethanol (C8H21N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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), 2,2'-((2-((2-Aminoethyl)amino)ethyl)azanediyl)diethanol 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.
