Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[2-[(tert-Butoxycarbonyl)amino]ethoxy]ethanol.
CATO supplies 2-[2-[(tert-Butoxycarbonyl)amino]ethoxy]ethanol (CAS 139115-91-6), a certified reference material (molecular formula C9H19NO4, MW 205.25 g/mol) for analytical method development and quality control.
Structurally, 2-[2-[(tert-Butoxycarbonyl)amino]ethoxy]ethanol (C9H19NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 205.25 g/mol, it falls into the medium-molecular-weight range. 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.
