Chemical Structure
Description
6-(Bromomethyl)-1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene (CAS 119435-90-4) is a high-purity analytical reference standard with the molecular formula C15H21Br and a molecular weight of 281.23 g/mol.
6-(Bromomethyl)-1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene (C15H21Br) 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. 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), 6-(Bromomethyl)-1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene 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.
