N-(2,2,2-Trifluoroacetyl)-L-aspartic acid CAS 369-08-4

Description

Compared with other compounds in its class, the molecular weight of 229.11 g/mol gives N-(2,2,2-Trifluoroacetyl)-L-aspartic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(2,2,2-Trifluoroacetyl)-L-aspartic acid (CAS 369-08-4), molecular formula C6H6F3NO5 and molecular weight 229.11 g/mol, is a CATO reference standard with documented purity and traceability.

N-(2,2,2-Trifluoroacetyl)-L-aspartic acid (C6H6F3NO5) contains a carbohydrate-derived structure, an amide group, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
