Chemical Structure
Description
The occurrence of 2-Bromo-2’,4’,6’-trimethylacetophenone is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-2’,4’,6’-trimethylacetophenone (CAS 4225-92-7) is a high-purity analytical reference standard with the molecular formula C11H13BrO and a molecular weight of 241.12 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-2’,4’,6’-trimethylacetophenone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 241.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-2’,4’,6’-trimethylacetophenone 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.
