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,5R)-3-(Tert-butyl)-3-methyl-5-phenylmorpholin-2-one.
CATO supplies (3R,5R)-3-(Tert-butyl)-3-methyl-5-phenylmorpholin-2-one (CAS 185537-77-3), a certified reference material (molecular formula C15H21NO2, MW 247.33 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (3R,5R)-3-(Tert-butyl)-3-methyl-5-phenylmorpholin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.33 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.
As a certified reference material (CRM), (3R,5R)-3-(Tert-butyl)-3-methyl-5-phenylmorpholin-2-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.
