Chemical Structure
Description
CATO supplies Ethyl 2-(4-(4-(2-bromo-2-methylpropanoyl)phenyl)cyclohexyl)acetate (CAS 701232-18-0), a certified reference material (molecular formula C20H27BrO3, MW 395.33 g/mol) for analytical method development and quality control.
Ethyl 2-(4-(4-(2-bromo-2-methylpropanoyl)phenyl)cyclohexyl)acetate (C20H27BrO3) 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, the carboxyl group imparts weak acidity; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
