Description
32025-65-3 3-Methoxyphenylglyoxal Benzeneacetaldehyde, 3-methoxy-alpha-oxo-, hemihydrate AI3-25049 meta-Methoxyphenylglyoxal (CAS 32025-65-3) is a high-purity analytical reference standard with the molecular formula C9H8O3 and a molecular weight of 164.16 g/mol.
The molecular framework of 32025-65-3 3-Methoxyphenylglyoxal Benzeneacetaldehyde, 3-methoxy-alpha-oxo-, hemihydrate AI3-25049 meta-Methoxyphenylglyoxal (C9H8O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 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.
As a certified reference material (CRM), 32025-65-3 3-Methoxyphenylglyoxal Benzeneacetaldehyde, 3-methoxy-alpha-oxo-, hemihydrate AI3-25049 meta-Methoxyphenylglyoxal 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.
