4-Methoxy-6-methyl-5,6-dihydro-2H-pyran-2-one CAS 3791-79-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 4-Methoxy-6-methyl-5,6-dihydro-2H-pyran-2-one (CAS 3791-79-5), a certified reference material (molecular formula C7H10O3, MW 142.15 g/mol) for analytical method development and quality control.

Structurally, 4-Methoxy-6-methyl-5,6-dihydro-2H-pyran-2-one (C7H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 142.15 g/mol, it falls into the low-molecular-weight range. 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).

CATO manufactures 4-Methoxy-6-methyl-5,6-dihydro-2H-pyran-2-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.
