Chemical Structure
Description
The occurrence of 1-(1-Bromoethyl)-4-tert-butylbenzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(1-Bromoethyl)-4-tert-butylbenzene (CAS 157581-03-8), molecular formula C12H17Br and molecular weight 241.17 g/mol, is a CATO reference standard with documented purity and traceability.
1-(1-Bromoethyl)-4-tert-butylbenzene (C12H17Br) contains bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1-(1-Bromoethyl)-4-tert-butylbenzene 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.
