86770-74-3 Ethanol, 2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)- T4EGMA 2-(2-(2-(2-Aminoethoxy)ethoxy)ethoxy)ethanol Tetraethylene glycol monoamine (CAS 86770-74-3) is a high-purity analytical reference standard with the molecular formula C8H19NO4 and a molecular weight of 193.24 g/mol.
86770-74-3 Ethanol, 2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)- T4EGMA 2-(2-(2-(2-Aminoethoxy)ethoxy)ethoxy)ethanol Tetraethylene glycol monoamine (C8H19NO4) 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.
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.
