Chemical Structure
Description
CATO supplies 3-(2-chlorophenoxy)-2-butanone (CAS 3757-62-8), a certified reference material (molecular formula C10H11ClO2, MW 198.65 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H11ClO2, 3-(2-chlorophenoxy)-2-butanone 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 198.65 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.
As a certified reference material (CRM), 3-(2-chlorophenoxy)-2-butanone 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.
