Chemical Structure
Description
Structurally, (2R)-1-Carbamimidoyl-3-hydroxy-2-methylpyrrolidine-2-carboxylic acid (C6H11N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 173.17 g/mol, it falls into the medium-molecular-weight range. 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).
(2R)-1-Carbamimidoyl-3-hydroxy-2-methylpyrrolidine-2-carboxylic acid (CAS 67736-29-2) is a high-purity analytical reference standard with the molecular formula C6H11N3O3 and a molecular weight of 173.17 g/mol.
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.
