Description

The occurrence of (2S)-2-(tert-butoxycarbonylamino)-3-hydroxy-2-methyl-propanoic acid (2S)-2-(tert-butoxycarbonylamino)-3-hydroxy-2-methyl-propionic acid (2S)-2-methyl-2-[(2-methylpropan-2-yl)oxycarbonylamino]-3-oxidanyl-propanoic acid (2S)-3-hydroxy-2-methyl-2-[(2-methylpropan-2-yl)oxycarbonylamino]propanoic acid (2S)-3-hydroxy-2-methyl-2-[[(2-methylpropan-2-yl)oxy-oxomethyl]amino]propanoic acid 84311-19-3 Boc-(S)-2-amino-2-methyl-3-hydroxypropanoic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2S)-2-(tert-butoxycarbonylamino)-3-hydroxy-2-methyl-propanoic acid (2S)-2-(tert-butoxycarbonylamino)-3-hydroxy-2-methyl-propionic acid (2S)-2-methyl-2-[(2-methylpropan-2-yl)oxycarbonylamino]-3-oxidanyl-propanoic acid (2S)-3-hydroxy-2-methyl-2-[(2-methylpropan-2-yl)oxycarbonylamino]propanoic acid (2S)-3-hydroxy-2-methyl-2-[[(2-methylpropan-2-yl)oxy-oxomethyl]amino]propanoic acid 84311-19-3 Boc-(S)-2-amino-2-methyl-3-hydroxypropanoic acid (CAS 84311-19-3) is a high-purity analytical reference standard with the molecular formula C9H17NO5 and a molecular weight of 219.23 g/mol.

Based on its molecular formula C9H17NO5, (2S)-2-(tert-butoxycarbonylamino)-3-hydroxy-2-methyl-propanoic acid (2S)-2-(tert-butoxycarbonylamino)-3-hydroxy-2-methyl-propionic acid (2S)-2-methyl-2-[(2-methylpropan-2-yl)oxycarbonylamino]-3-oxidanyl-propanoic acid (2S)-3-hydroxy-2-methyl-2-[(2-methylpropan-2-yl)oxycarbonylamino]propanoic acid (2S)-3-hydroxy-2-methyl-2-[[(2-methylpropan-2-yl)oxy-oxomethyl]amino]propanoic acid 84311-19-3 Boc-(S)-2-amino-2-methyl-3-hydroxypropanoic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 219.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
