Description
As a certified reference material (CRM), 6-Acetyl-5-hydroxy-2-methylbenzofuran-3-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-Acetyl-5-hydroxy-2-methylbenzofuran-3-carboxylic acid (CAS 63529-83-9) is a high-purity analytical reference standard with the molecular formula C12H10O5 and a molecular weight of 234.20 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 6-Acetyl-5-hydroxy-2-methylbenzofuran-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
