4-Hydroxy-3,4-dihydro-2H-pyran-2-one CAS 112592-82-2

Description

The occurrence of 4-Hydroxy-3,4-dihydro-2H-pyran-2-one 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-Hydroxy-3,4-dihydro-2H-pyran-2-one (CAS 112592-82-2), molecular formula C5H6O3 and molecular weight 114.10 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H6O3, 4-Hydroxy-3,4-dihydro-2H-pyran-2-one contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 114.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-Hydroxy-3,4-dihydro-2H-pyran-2-one 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.
