Chemical Structure
Description
The occurrence of 2-Chloro-1-(pyrrolidin-1-yl)butan-1-one is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Chloro-1-(pyrrolidin-1-yl)butan-1-one (CAS 666853-58-3), a certified reference material (molecular formula C8H14ClNO, MW 175.66 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-1-(pyrrolidin-1-yl)butan-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Chloro-1-(pyrrolidin-1-yl)butan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
