Chemical Structure

(S)-2-(1H-imidazol-1-yl)propanoic acid CAS 1007349-05-4 chemical structure

Description

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.

(S)-2-(1H-imidazol-1-yl)propanoic acid (CAS 1007349-05-4) is a high-purity analytical reference standard with the molecular formula C6H8N2O2 and a molecular weight of 140.14 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (S)-2-(1H-imidazol-1-yl)propanoic acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
