Chemical Structure

4,6,6-Trimethyl-5,6-dihydro-2H-pyran-2-one CAS 6970-56-5 chemical structure

Description

CATO manufactures 4,6,6-Trimethyl-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.

CATO supplies 4,6,6-Trimethyl-5,6-dihydro-2H-pyran-2-one (CAS 6970-56-5), a certified reference material (molecular formula C8H12O2, MW 140.18 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4,6,6-Trimethyl-5,6-dihydro-2H-pyran-2-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
