Chemical Structure
Description
The molecular framework of Acetyl-L-leucyl-L-lysine·TFA (C14H27N3O4C2HF3O2) 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.
Acetyl-L-leucyl-L-lysine·TFA (CAS 1408278-89-6(Free Base)) is a high-purity analytical reference standard with the molecular formula C14H27N3O4C2HF3O2 and a molecular weight of 415.41 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Acetyl-L-leucyl-L-lysine·TFA 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.
