(1R,3R)-5-(Bromomethylene)-1,3-bis(tert-butyldimethylsilyloxy)cyclohexane (CAS 387834-41-5), molecular formula C19H39BrO2Si2 and molecular weight 435.59 g/mol, is a CATO reference standard with documented purity and traceability.
(1R,3R)-5-(Bromomethylene)-1,3-bis(tert-butyldimethylsilyloxy)cyclohexane (C19H39BrO2Si2) contains a carboxylic acid group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
