(S)-(-)-2-(Trifluoroacetamido)succinic anhydride (S)-(-)-2-Trifluoroacetamidosuccinic anhydride 777-33-3 N-Trifluoroacetyl-L-aspartic acid anhydride (CAS 777-33-3) is a high-purity analytical reference standard with the molecular formula C6H4F3NO4 and a molecular weight of 211.10 g/mol.
The molecular framework of (S)-(-)-2-(Trifluoroacetamido)succinic anhydride (S)-(-)-2-Trifluoroacetamidosuccinic anhydride 777-33-3 N-Trifluoroacetyl-L-aspartic acid anhydride (C6H4F3NO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. 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.
