Chemical Structure
Description
The occurrence of 4-methoxyfuran-2(5H)-one 69556-70-3 Methyl tetronate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-methoxyfuran-2(5H)-one 69556-70-3 Methyl tetronate (CAS 69556-70-3), molecular formula C5H6O3 and molecular weight 114.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-methoxyfuran-2(5H)-one 69556-70-3 Methyl tetronate (C5H6O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-methoxyfuran-2(5H)-one 69556-70-3 Methyl tetronate 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.
