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 2,2,5,6-Tetramethyl-4H-1,3-dioxin-4-one (CAS 87769-39-9), a certified reference material (molecular formula C8H12O3, MW 156.18 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,2,5,6-Tetramethyl-4H-1,3-dioxin-4-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.18 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).
CATO manufactures 2,2,5,6-Tetramethyl-4H-1,3-dioxin-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.
