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 (3R,4R)-3-ethynyl-3-hydroxy-1,4-dimethyl-pyrrolidin-2-one.
CATO supplies (3R,4R)-3-ethynyl-3-hydroxy-1,4-dimethyl-pyrrolidin-2-one (CAS 2561461-48-9), a certified reference material (molecular formula C8H11NO2, MW 153.18 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (3R,4R)-3-ethynyl-3-hydroxy-1,4-dimethyl-pyrrolidin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 153.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
