(2S,3R)-2-Amino-3-methylpentanedioic acid CAS 33511-69-2

Description

The occurrence of (2S,3R)-2-Amino-3-methylpentanedioic 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,3R)-2-Amino-3-methylpentanedioic acid (CAS 33511-69-2) is a high-purity analytical reference standard with the molecular formula C6H11NO4 and a molecular weight of 161.16 g/mol.

Based on its molecular formula C6H11NO4, (2S,3R)-2-Amino-3-methylpentanedioic 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 161.16 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.
