Chemical Structure
Description
The occurrence of 1,5-Dibromo-3-(tert-butyl)-2-methoxybenzene 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.
1,5-Dibromo-3-(tert-butyl)-2-methoxybenzene (CAS 31918-99-7) is a high-purity analytical reference standard with the molecular formula C11H14Br2O and a molecular weight of 322.04 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1,5-Dibromo-3-(tert-butyl)-2-methoxybenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1,5-Dibromo-3-(tert-butyl)-2-methoxybenzene 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.
