Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 2-(5-hydroxy-4,7-dimethyl-2-oxo-2H-chromen-3-yl)acetate (CAS 710990-95-7) is a high-purity analytical reference standard with the molecular formula C14H14O5 and a molecular weight of 262.26 g/mol.
The molecular framework of Methyl 2-(5-hydroxy-4,7-dimethyl-2-oxo-2H-chromen-3-yl)acetate (C14H14O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
As a certified reference material (CRM), Methyl 2-(5-hydroxy-4,7-dimethyl-2-oxo-2H-chromen-3-yl)acetate 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.
