Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 198.65 g/mol gives 2-Chloro-1-(2-ethoxyphenyl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-1-(2-ethoxyphenyl)ethan-1-one (CAS 1243783-56-3), molecular formula C10H11ClO2 and molecular weight 198.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-1-(2-ethoxyphenyl)ethan-1-one (C10H11ClO2) is characterized by a carboxylic acid group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
