Chemical Structure
Description
The molecular framework of 161829-91-0 5-Chloro-1-(2,4-dichlorophenyl)pentan-1-one DTXSID20645174 (C11H11Cl3O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 161829-91-0 5-Chloro-1-(2,4-dichlorophenyl)pentan-1-one DTXSID20645174 (CAS 161829-91-0), a certified reference material (molecular formula C11H11Cl3O, MW 265.56 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.
