Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 151.59 g/mol gives (R)-2-amino-3-methylbut-3-enoic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-2-amino-3-methylbut-3-enoic acid hydrochloride (CAS 60103-01-7) is a high-purity analytical reference standard with the molecular formula C5H9NO2HCl and a molecular weight of 151.59 g/mol.
Structurally, (R)-2-amino-3-methylbut-3-enoic acid hydrochloride (C5H9NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 151.59 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.
