Chemical Structure
Description
The occurrence of 1-Bromo-4-(2-bromoethyl)-2-methylbenzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-4-(2-bromoethyl)-2-methylbenzene (CAS 1514058-22-0), molecular formula C9H10Br2 and molecular weight 277.98 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, an aromatic ring system, 1-Bromo-4-(2-bromoethyl)-2-methylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.98 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-Bromo-4-(2-bromoethyl)-2-methylbenzene 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.
