Chemical Structure
Description
As a certified reference material (CRM), 1-(5-Chloro-2-ethylphenyl)ethanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1-(5-Chloro-2-ethylphenyl)ethanone (CAS 1783576-49-7) is a high-purity analytical reference standard with the molecular formula C10H11ClO and a molecular weight of 182.65 g/mol.
1-(5-Chloro-2-ethylphenyl)ethanone (C10H11ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
