Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
898791-67-8 6-(4-Ethoxyphenyl)-6-oxohexanoic acid DTXSID80645438 (CAS 898791-67-8) is a high-purity analytical reference standard with the molecular formula C14H18O4 and a molecular weight of 250.29 g/mol.
The molecular framework of 898791-67-8 6-(4-Ethoxyphenyl)-6-oxohexanoic acid DTXSID80645438 (C14H18O4) 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).
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.
