Description
CATO supplies 6-Bromo-1,1,4,4-tetramethyl-7-(pentyloxy)-1,2,3,4-tetrahydronaphthalene (CAS 191157-23-0), a certified reference material (molecular formula C19H29BrO, MW 353.34 g/mol) for analytical method development and quality control.
6-Bromo-1,1,4,4-tetramethyl-7-(pentyloxy)-1,2,3,4-tetrahydronaphthalene (C19H29BrO) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. 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), 6-Bromo-1,1,4,4-tetramethyl-7-(pentyloxy)-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.
