Chemical Structure
Description
Structurally, 2-Oxo-4-phenyl-pyrrolidine-3-carboxylic acid 2-oxo-4-phenylpyrrolidine-3-carboxylic acid 77519-55-2 (C11H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 205.21 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-Oxo-4-phenyl-pyrrolidine-3-carboxylic acid 2-oxo-4-phenylpyrrolidine-3-carboxylic acid 77519-55-2 (CAS 77519-55-2) is a high-purity analytical reference standard with the molecular formula C11H11NO3 and a molecular weight of 205.21 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
