(S)-2-((2R,6R)-2,6-Dimethyltetrahydro-2H-pyran-4-yl)-2-((methoxycarbonyl)amino)acetic acid CAS 1359976-83-2 chemical structure

Description

The occurrence of (S)-2-((2R,6R)-2,6-Dimethyltetrahydro-2H-pyran-4-yl)-2-((methoxycarbonyl)amino)acetic 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.

(S)-2-((2R,6R)-2,6-Dimethyltetrahydro-2H-pyran-4-yl)-2-((methoxycarbonyl)amino)acetic acid (CAS 1359976-83-2) is a high-purity analytical reference standard with the molecular formula C11H19NO5 and a molecular weight of 245.27 g/mol.

Based on its molecular formula C11H19NO5, (S)-2-((2R,6R)-2,6-Dimethyltetrahydro-2H-pyran-4-yl)-2-((methoxycarbonyl)amino)acetic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 245.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
