Chemical Structure

4<I>H</I>-pyran-4-one CAS 108-97-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 96.08 g/mol gives 4<I>H</I>-pyran-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4<I>H</I>-pyran-4-one (CAS 108-97-4) is a high-purity analytical reference standard with the molecular formula C5H4O2 and a molecular weight of 96.08 g/mol.

The molecular framework of 4<I>H</I>-pyran-4-one (C5H4O2) 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.

CATO manufactures 4<I>H</I>-pyran-4-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
