Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 171.60 g/mol gives (S)-4-Amino-5-fluoropentanoic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-4-Amino-5-fluoropentanoic acid hydrochloride (CAS 72522-16-8) is a high-purity analytical reference standard with the molecular formula C5H10FNO2HCl and a molecular weight of 171.60 g/mol.
(S)-4-Amino-5-fluoropentanoic acid hydrochloride (C5H10FNO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
