Chemical Structure
Description
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.
N-[(S)-1-(2-Chloro-acetyl)-pyrrolidin-3-yl]-N-methyl-acetamide (CAS 1353945-71-7) is a high-purity analytical reference standard with the molecular formula C11H19ClN2O2 and a molecular weight of 246.73 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, N-[(S)-1-(2-Chloro-acetyl)-pyrrolidin-3-yl]-N-methyl-acetamide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
