Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.24 g/mol gives Boc-cis-4-fluoro-Pro-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Boc-cis-4-fluoro-Pro-OH (CAS 203866-13-1), a certified reference material (molecular formula C10H16FNO4, MW 233.24 g/mol) for analytical method development and quality control.
The molecular framework of Boc-cis-4-fluoro-Pro-OH (C10H16FNO4) 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.
