(R)-3-Amino-2-methyl-butan-2-ol hydrochloride CAS 157769-82-9

Description

Compared with other compounds in its class, the molecular weight of 139.62 g/mol gives (R)-3-Amino-2-methyl-butan-2-ol hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-3-Amino-2-methyl-butan-2-ol hydrochloride (CAS 157769-82-9) is a high-purity analytical reference standard with the molecular formula C5H13NOHCl and a molecular weight of 139.62 g/mol.

Based on its molecular formula C5H13NOHCl, (R)-3-Amino-2-methyl-butan-2-ol hydrochloride contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 139.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
