As a certified reference material (CRM), 1-Chloro-3-ethoxypropan-2-one 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-Chloro-3-ethoxypropan-2-one (CAS 69378-63-8) is a high-purity analytical reference standard with the molecular formula C5H9ClO2 and a molecular weight of 136.58 g/mol.
The molecular framework of 1-Chloro-3-ethoxypropan-2-one (C5H9ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
