Chemical Structure
Description
CATO supplies Ethyl 8-(3,5-dichlorophenyl)-8-oxooctanoate (CAS 898751-96-7), a certified reference material (molecular formula C16H20Cl2O3, MW 331.23 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H20Cl2O3, Ethyl 8-(3,5-dichlorophenyl)-8-oxooctanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 331.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
