Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-[3-Methoxy-3-oxo-2-(1-oxo-2,3-dihydro-1H-isoindol-2-yl)propyl]phenyl 2-methylbenzoate (CAS 477889-63-7) is a high-purity analytical reference standard with the molecular formula C26H23NO5 and a molecular weight of 429.46 g/mol.
4-[3-Methoxy-3-oxo-2-(1-oxo-2,3-dihydro-1H-isoindol-2-yl)propyl]phenyl 2-methylbenzoate (C26H23NO5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-[3-Methoxy-3-oxo-2-(1-oxo-2,3-dihydro-1H-isoindol-2-yl)propyl]phenyl 2-methylbenzoate 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.
