Chemical Structure

H-Thr-Ser-Lys-OH·xTFA salt CAS 71730-64-8 chemical structure

Description

The occurrence of H-Thr-Ser-Lys-OH·xTFA salt is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies H-Thr-Ser-Lys-OH·xTFA salt (CAS 71730-64-8), a certified reference material (molecular formula C13H26N4O6C2HF3O2, MW 448.39 g/mol) for analytical method development and quality control.

The molecular framework of H-Thr-Ser-Lys-OH·xTFA salt (C13H26N4O6C2HF3O2) 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.

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.
