4-Oxo-4H-pyran-2-carbaldehyde CAS 56683-22-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Oxo-4H-pyran-2-carbaldehyde.

4-Oxo-4H-pyran-2-carbaldehyde (CAS 56683-22-8), molecular formula C6H4O3 and molecular weight 124.09 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Oxo-4H-pyran-2-carbaldehyde (C6H4O3) 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 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).

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), 4-Oxo-4H-pyran-2-carbaldehyde 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.
