Chemical Structure
Description
As a certified reference material (CRM), Ethyl 5-ethyl-2-methylfuran-3-carboxylate 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.
Ethyl 5-ethyl-2-methylfuran-3-carboxylate (CAS 64354-20-7), molecular formula C10H14O3 and molecular weight 182.22 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 5-ethyl-2-methylfuran-3-carboxylate (C10H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
