Description

Compared with other compounds in its class, the molecular weight of 207.22 g/mol gives 2-[2-[2-(2-Aminoethoxy)ethoxy]ethoxy]acetic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-[2-[2-(2-Aminoethoxy)ethoxy]ethoxy]acetic Acid (CAS 134978-99-7), molecular formula C8H17NO5 and molecular weight 207.22 g/mol, is a CATO reference standard with documented purity and traceability.

2-[2-[2-(2-Aminoethoxy)ethoxy]ethoxy]acetic Acid (C8H17NO5) 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.

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.
