Chemical Structure
Description
898758-32-2 Ethyl 6-(2,5-dimethoxyphenyl)-6-oxohexanoate DTXSID40645818 (C16H22O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 898758-32-2 Ethyl 6-(2,5-dimethoxyphenyl)-6-oxohexanoate DTXSID40645818 (CAS 898758-32-2), a certified reference material (molecular formula C16H22O5, MW 294.34 g/mol) for analytical method development and quality control.
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.
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.
