Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 219.16 g/mol gives (3-Bromo-2-methylpropyl)cyclohexane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3-Bromo-2-methylpropyl)cyclohexane (CAS 21782-55-8), a certified reference material (molecular formula C10H19Br, MW 219.16 g/mol) for analytical method development and quality control.
(3-Bromo-2-methylpropyl)cyclohexane (C10H19Br) contains 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (3-Bromo-2-methylpropyl)cyclohexane 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.
