Chemical Structure

Ethyl bicyclo[2.2.2]octa-2,5-diene-2-carboxylate CAS 39863-21-3 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 bicyclo[2.2.2]octa-2,5-diene-2-carboxylate.

Ethyl bicyclo[2.2.2]octa-2,5-diene-2-carboxylate (CAS 39863-21-3) is a high-purity analytical reference standard with the molecular formula C11H14O2 and a molecular weight of 178.23 g/mol.

The molecular framework of Ethyl bicyclo[2.2.2]octa-2,5-diene-2-carboxylate (C11H14O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
