(S)-Methyl 2-amino-3-(1H-pyrazol-1-yl)propanoate CAS 740736-19-0

Description

The occurrence of (S)-Methyl 2-amino-3-(1H-pyrazol-1-yl)propanoate 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)-Methyl 2-amino-3-(1H-pyrazol-1-yl)propanoate (CAS 740736-19-0) is a high-purity analytical reference standard with the molecular formula C7H11N3O2 and a molecular weight of 169.18 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (S)-Methyl 2-amino-3-(1H-pyrazol-1-yl)propanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
