Chemical Structure
Description
The occurrence of 2-Bromo-4,4-dimethylcyclohexane-1,3-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Bromo-4,4-dimethylcyclohexane-1,3-dione (CAS 476415-35-7), a certified reference material (molecular formula C8H11BrO2, MW 219.08 g/mol) for analytical method development and quality control.
2-Bromo-4,4-dimethylcyclohexane-1,3-dione (C8H11BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-Bromo-4,4-dimethylcyclohexane-1,3-dione 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.
