Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-oxaspiro[5.5]undecan-9-one.
CATO supplies 3-oxaspiro[5.5]undecan-9-one (CAS 1159280-53-1), a certified reference material (molecular formula C10H16O2, MW 168.23 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-oxaspiro[5.5]undecan-9-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.23 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), 3-oxaspiro[5.5]undecan-9-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.
