Chemical Structure
Description
As a certified reference material (CRM), 6-Acetylbenzofuran-2-carboxylic acid 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.
6-Acetylbenzofuran-2-carboxylic acid (CAS 2756972-21-9), molecular formula C11H8O4 and molecular weight 204.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Acetylbenzofuran-2-carboxylic acid (C11H8O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 204.18 g/mol, it falls into the medium-molecular-weight range. 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.
