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 Methyl 2-oxo-2-(5-oxo-5,6,7,8,9,10-hexahydrobenzo[8]annulen-6-yl)acetate.
Methyl 2-oxo-2-(5-oxo-5,6,7,8,9,10-hexahydrobenzo[8]annulen-6-yl)acetate (CAS 2055840-45-2) is a high-purity analytical reference standard with the molecular formula C15H16O4 and a molecular weight of 260.29 g/mol.
The molecular framework of Methyl 2-oxo-2-(5-oxo-5,6,7,8,9,10-hexahydrobenzo[8]annulen-6-yl)acetate (C15H16O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
