Chemical Structure
Description
As a certified reference material (CRM), (E)-3-(1-Oxo-1H-benzo[f]chromen-2-yl)acrylaldehyde 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.
(E)-3-(1-Oxo-1H-benzo[f]chromen-2-yl)acrylaldehyde (CAS 124980-79-6), molecular formula C16H10O3 and molecular weight 250.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-3-(1-Oxo-1H-benzo[f]chromen-2-yl)acrylaldehyde (C16H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 250.25 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
