Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies tert-Butyl 3-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)piperidine-1-carboxylate (CAS 1190890-10-8), a certified reference material (molecular formula C18H22N2O4, MW 330.38 g/mol) for analytical method development and quality control.
The molecular framework of tert-Butyl 3-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)piperidine-1-carboxylate (C18H22N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), tert-Butyl 3-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)piperidine-1-carboxylate 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.
