Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4R)-4-hydroxy-2-pyrrolidinone (4R)-4-oxidanylpyrrolidin-2-one 22677-21-0 A816305.
(4R)-4-hydroxy-2-pyrrolidinone (4R)-4-oxidanylpyrrolidin-2-one 22677-21-0 A816305 (CAS 22677-21-0) is a high-purity analytical reference standard with the molecular formula C4H7NO2 and a molecular weight of 101.10 g/mol.
(4R)-4-hydroxy-2-pyrrolidinone (4R)-4-oxidanylpyrrolidin-2-one 22677-21-0 A816305 (C4H7NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
