(S)-2-((S)-2-Aminopropanamido)-3-methylbutanoic acid 2,2,2-trifluoroacetate CAS 76615-36-6

Description

(S)-2-((S)-2-Aminopropanamido)-3-methylbutanoic acid 2,2,2-trifluoroacetate (CAS 76615-36-6) is a high-purity analytical reference standard with the molecular formula C8H16N2O3C2HF3O2 and a molecular weight of 302.25 g/mol.

The molecular framework of (S)-2-((S)-2-Aminopropanamido)-3-methylbutanoic acid 2,2,2-trifluoroacetate (C8H16N2O3C2HF3O2) 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.

As a certified reference material (CRM), (S)-2-((S)-2-Aminopropanamido)-3-methylbutanoic acid 2,2,2-trifluoroacetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
