Chemical Structure
Description
CATO supplies 1-(4-Amino-3-chlorophenyl)pyrrolidin-2-one (CAS 1101046-66-5), a certified reference material (molecular formula C10H11ClN2O, MW 210.66 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H11ClN2O, 1-(4-Amino-3-chlorophenyl)pyrrolidin-2-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 210.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
