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.
ethyl 2-(tert-butoxycarbonylamino)-4,4,4-trifluoro-butanoate (CAS 2322231-10-5) is a high-purity analytical reference standard with the molecular formula C11H18F3NO4 and a molecular weight of 285.26 g/mol.
The molecular framework of ethyl 2-(tert-butoxycarbonylamino)-4,4,4-trifluoro-butanoate (C11H18F3NO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
