Description
As a certified reference material (CRM), 2-Acetyl-3H-benzo[f]chromen-3-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.
2-Acetyl-3H-benzo[f]chromen-3-one (CAS 727-80-0), molecular formula C15H10O3 and molecular weight 238.24 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H10O3, 2-Acetyl-3H-benzo[f]chromen-3-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.24 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.
