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 ethyl 2-oxo-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acetate.
ethyl 2-oxo-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acetate (CAS 5803-71-4) is a high-purity analytical reference standard with the molecular formula C14H16O3 and a molecular weight of 232.28 g/mol.
The molecular framework of ethyl 2-oxo-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acetate (C14H16O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures ethyl 2-oxo-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
