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 2-Chloro-1-(2,2-dimethylpyrrolidin-1-yl)ethan-1-one.
2-Chloro-1-(2,2-dimethylpyrrolidin-1-yl)ethan-1-one (CAS 919111-20-9) is a high-purity analytical reference standard with the molecular formula C8H14ClNO and a molecular weight of 175.66 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-1-(2,2-dimethylpyrrolidin-1-yl)ethan-1-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
