Description
As a certified reference material (CRM), Ethyl 1-oxo-7-(tetramethyl-1,3,2-dioxaborolan-2-yl)-3,4-dihydro-2H-naphthalene-2-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.
Ethyl 1-oxo-7-(tetramethyl-1,3,2-dioxaborolan-2-yl)-3,4-dihydro-2H-naphthalene-2-carboxylate (CAS 2377587-51-2) is a high-purity analytical reference standard with the molecular formula C19H25BO5 and a molecular weight of 344.21 g/mol.
The molecular framework of Ethyl 1-oxo-7-(tetramethyl-1,3,2-dioxaborolan-2-yl)-3,4-dihydro-2H-naphthalene-2-carboxylate (C19H25BO5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
