Description

The occurrence of 1-benzylpyrrolidin-2-one 2-pyrrolidinone, 1-(phenylmethyl)- 5291-77-0 InChI=1/C11H13NO/c13-11-7-4-8-12(11)9-10-5-2-1-3-6-10/h1-3,5-6H,4,7-9H is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-benzylpyrrolidin-2-one 2-pyrrolidinone, 1-(phenylmethyl)- 5291-77-0 InChI=1/C11H13NO/c13-11-7-4-8-12(11)9-10-5-2-1-3-6-10/h1-3,5-6H,4,7-9H (CAS 5291-77-0) is a high-purity analytical reference standard with the molecular formula C11H19NO and a molecular weight of 181.27 g/mol.

Based on its molecular formula C11H19NO, 1-benzylpyrrolidin-2-one 2-pyrrolidinone, 1-(phenylmethyl)- 5291-77-0 InChI=1/C11H13NO/c13-11-7-4-8-12(11)9-10-5-2-1-3-6-10/h1-3,5-6H,4,7-9H contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 181.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
