Chemical Structure
Description
The occurrence of (R)-2-((tert-Butoxycarbonyl)amino)-3-fluoropropanoic acid 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 (R)-2-((tert-Butoxycarbonyl)amino)-3-fluoropropanoic acid (CAS 76399-81-0), a certified reference material (molecular formula C8H14FNO4, MW 207.20 g/mol) for analytical method development and quality control.
Structurally, (R)-2-((tert-Butoxycarbonyl)amino)-3-fluoropropanoic acid (C8H14FNO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 207.20 g/mol, it falls into the medium-molecular-weight range. 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.
