Chemical Structure
Description
CATO supplies 5-Bromo-2,2,5-trimethyl-1,3-dioxane-4,6-dione (CAS 34817-42-0), a certified reference material (molecular formula C7H9BrO4, MW 237.05 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-2,2,5-trimethyl-1,3-dioxane-4,6-dione (C7H9BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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 5-Bromo-2,2,5-trimethyl-1,3-dioxane-4,6-dione 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.
